2013 International Conference on Embedded Computer Systems: Architectures, Modeling, and Simulation (SAMOS XIII)

SAMOS is a unique conference. It deals with embedded systems (sort of) but that is not what makes it different. It brings together every year researchers from both academia and industry on the quiet and inspiring northern mountainside of the Mediterranean island of Samos, which in itself is different. But more importantly, it really fosters collaboration rather than competition. Formal and intensive technical sessions are only held in the mornings. A lively panel ends the formal part of the day, and leads nicely into the afternoons and evenings -- reserved for informal discussions, good food, and the inviting Aegean Sea.


2010 International Waveform Diversity and Design Conference (WDD)

This fifth conference in the on-going series will continue to build on the success of the previous four conferences by bringing together researchers from numerous diverse backgrounds and specialties to facilitate the exchange and cross-fertilization of ideas and research. Recent advances in hardware technology are enabling a much wider range of design freedoms to be explored for sensor and communication systems. As a result, there are emerging and compelling changes in system requirements such as more effic

  • Software defined radio based receivers using RTL — SDR: A review

    Software defined Radio is one of the most important and latest technique for modern wireless communication. SDR is a radio which can be tuned to any frequency band which the hardware supports, implement different modulation and demodulation schemes and different signal types and standard(s) in the same device by using reconfigurable hardware and using powerful software. This paper provides a detailed analysis of SDR based radio receivers that can be implemented by using SDR systems. The main types of devices that can be implemented using SDR are only Radio Receiver, only Radio Transmitter and a Transceiver which provide function for both transmitter and receiver. Implementation of SDR devices using MATLAB, Simulink, GNU Radio and Single Board Computer is also discussed in this paper. The availability of low cost SDR hardware with good functional capability has reduced the overall cost of SDR system. This paper also provides a comparison between different types of radio systems developed using SDR and their performance analysis is also provided.

The USRPs designed by Ettus Research are used without a deep knowledge of their performances. In this paper, we report our output power measurements using a USRP B210 driven by a GNU Radio program. Our results show that the obtained output power decreases as the selected central frequency increases. We unveiled the impact of USRP Hardware Driver (UHD) of the GNU Radio on output power of a USRP B210.

  • Low cost digital transceiver design for Software Defined Radio using RTL-SDR

    The field of wireless communication has become the hottest area and Software Defined Radio (SDR) is revolutionizing it. By bringing much functionality as software, SDR reduces the cost of hardware maintenance and up-gradation. Open source hardware such as USRP (Universal Software Radio Peripheral) and software called GNU Radio-Companion are commonly used to do experiments in SDR. Since the cost of USRP is high, a low cost set up is needed which is affordable by the student community. In this paper a low cost alternative to USRP is proposed using RTL-SDR (Realtek Software Defined Radio) which is only used for reception. For transmitting purpose, a mixer circuit can be used to map the baseband signal to the band that can be received by RTL-SDR on the other end on Linux / Windows platform. Initially, the experiment is done in simulation. After that, it is tested with low cost hardware such as mixer and RTL-SDR. The cost for total transceiver system can be less than USD 100 which is 10 times less than the existing one.

  • Early Performance Estimation for Industrial Component-Based Design of Reliable Software Defined Radio System

    The growing complexity of software applications, combined with increasing reliability requirements and constant quality and time-to-market constraints, creates new challenges for performance engineering practices in the area of real-time embedded systems. It is namely expected that delivered products combine timing garantees with fault tolerant behavior, e.g. by switching to fault tolerant modes in case of errors, while respecting strict real-time requirements. When developing such real-time systems according to a traditional application of the "Va"-cycle, performance verification and validation activities start only when development and integration are completed. As a consequence, performance issues are detected at a late stage. At this time, they are more difficult and expensive to fix. At Thales, we have therefore focused on the automation of performance engineering activities and their application as early as possible in the industrial design process of reliable Software Defined Radio (SDR) systems, as a mean to shorten the design time and reduce risks of timing failures. The SDR particularity consists in implementing the signal modulation of a communication radio using software rather than hardware. It is namely much easier to reprogram the modulation carrier in order to fit different situations with the same hardware radio (e.g. each national army typically uses specific waveforms to guarantee the confidentiality of communications). The implementation of a reliable software waveform can be a difficult task, as it involves real-time constraints as well as embedded aspects while dealing with complex algorithms including those for fault recovery. Thales created a software framework family, named MyCCM (Make your Component Container Model), to support the implementation of such real- time embedded software. MyCCM is a tailorable component based design approach that takes inspiration from the Lightweight Component Container Model (LwCCM) defined by the OMG. It implements the concept of functional components that encapsulate algorithms. The components correspond to passive code controlled by an underlying runtime, and are connected through communication ports to create a complete application. This allows the construction of applications by assembling independent functional components. It also enforces the separation of concerns between the functional aspects described by component ports and the non functional elements that stay outside the components (message chaining across the whole component architecture, FIFO sizes, task priorities, communications mechanisms, execution times, etc). MyCCM models can be designed either using Thales internal modeling tools or using UML modelers with plain UML. Our developed framework for the early performance estimation of SDR MyCCM models is represented in the figure below. The first step consists in extending the SDR MyCCM model with performance properties, i.e. timing and behavior characteristics of the application (e.g. execution times and activation frequencies for threads and methods, data dependencies and communication protocols between threads) and execution characteristics of the hardware platform (e.g. speed, scheduling policy, etc). The OMG standard MARTE is key language for this purpose. However, due to the complexity of its syntax, it may result in very complex and confusing diagrams and models. We have therefore adapted the MARTE syntax based on the Thales SDR designers' feedback, thus allowing representing the performance properties in an easier and much more intuitive manner. We have opted for scheduling analysis techniques for the performance estimation of the extended MyCCM models, which is the next step in our framework. These techniques are well adapted for this purpose, since they rely on an abstraction of the timing relevant characteristics and behaviors. From these characteristics, the scheduling analysis systematically derives worst-case scheduling scenarios, and timing equations safely bound the worst-case response times. However, we faced the problem that scheduling analysis is not directly applicable to extended MyCCM models due to the semantic mismatch between the later and the variety of scheduling analysis models known from the classical real time systems research and from the industrial scheduling analysis tools. In order to fill this semantic gap and to ensure a minimum of independence from modeling and scheduling analysis tools, we have decided to introduce a pivot scheduling analysis model in-between. For this purpose, we have specified and implemented a set of rules transforming extended SDR MyCCM models into equivalent pivot scheduling analysis models and the later into the selected scheduling analysis tool models to which a dedicated SDR MyCCM scheduling analysis is applicable. Finally, we have defined and implemented rules adapting the scheduling analysis results to the original SDR MyCCM model.

  • Comparison of spectrum occupancy measurements using software defined radio RTL-SDR with a conventional spectrum analyzer approach

    In the present day Cognitive Radio has become a realistic option for solution of the spectrum scarcity problem in wireless communication. Recently, the TV band has attracted attention due to the considerable potential for exploitation of available TV white space which is not utilized based on time and location. In this paper, we investigate spectrum occupancy of the UHF TV band in the frequency range from 470 to 862MHz by using two different devices, the low cost device RTL-SDR and high cost spectrum analyzer. The spectrum occupancy measurements provide evidence of the utility of using the inexpensive RTL SDR and illustrate its effectiveness for detection of the percentage of spectrum utilization compared with results from the conventional high cost Agilent spectrum analyzer, both systems employing various antennas.

  • An empirical model of the SBX daughter board output power driven by USRP N210 and GNU radio based software defined radio

    In this paper, we propose an empirical model based on Radio Frequency (RF) measurements. The output power is measured sweeping a frequency band from 350 MHz to 4400 MHz of four SBX daughter boards [4]. These daughter boards are connected to a Universal Software Radio Peripheral (USRP) N210. For each carrier frequency, a narrow-band sinusoidal signal is generated by a GNU Radio Software Defined Radio (SDR). The output power at each carrier frequency is measured through a spectrum analyzer. Hence, an empirical model has been obtained to predict the output power in the analyzed frequency band.

  • An experimental study on RSS-based wireless localization with software defined radio

    Wireless localization has been an active research area over the last decade due to its endless applications. In this paper, we investigate received signal strength (RSS) based estimation of a mobile station's location, through monitoring the RSS at multiple reference software defined radio (SDR) receivers. Uplink transmission power of the mobile stations and path loss exponent are assumed to be unknown parameters. Universal software radio peripheral (USRP) devices are used to capture the RSS from uplink transmission of a mobile user. Subsequently, a linear least square localization technique is used to obtain the location estimate of the mobile station. Experiments with real mobile phones are conducted to demonstrate achievable localization accuracies in indoor environments with GSM technology.
