Best permutation search strategy for ultra-wideband signal acquisition

S. Vijayakumaran; T. F. Wong Vehicular Technology Conference, 2004. VTC2004-Fall. 2004 IEEE 60th, 2004

Recently, it was shown that equal gain combining (EGC) is a practical way of exploiting dense multipath in the ultra-wide band channel (UWB) to get better acquisition performance. By taking system performance subsequent to acquisition into account, it was shown that there are multiple phases (called the hit set) where a receiver lock can be considered as successful acquisition. In ...

This paper presents representative electromagnetic engineering applications of a particle swarm optimization (PSO) engine developed at UCLA antenna lab. The paper provides a conceptual overview of the PSO engine that accommodates real- number, binary, single-objective and multi-objective optimizations, along with five examples illustrated to validate the algorithm's functionality in a large variety of practical problems.

Optimum and suboptimum 8D-4P2C receivers

S. L. Drakul Military Communications Conference, 1996. MILCOM '96, Conference Proceedings, IEEE, 1996

The performance (error probability vs. Eb/N0) of a suboptimum sampling receiver used for detecting the 8D-4P2C signals is compared with a matched filter receiver. In addition, formulas for a selected set of modulation waveforms are derived, and the joint optimization of the transmitter and receiver is carried out for binary communications over a bandlimited Gaussian channel

M. N. Hadad; M. A. Funes; P. G. Donato; D. O. Carrica Argentine School of Micro-Nanoelectronics Technology and Applications (EAMTA), 2011, 2011

This work presents the implementation of improved architectures for simultaneous generation and correlation of mutually orthogonal complementary sets of sequences. By taking advantage of some redundancies in the generation and correlation algorithms, resources consumption is reduced and the performance of such architectures improved. The FPGA implementations performed with generic parameters is evaluated and compared with previous proposals.

Adriano Camps; Hyuk Park; Enric Valencia; Antonio Rius Geoscience and Remote Sensing Symposium (IGARSS), 2011 IEEE International, 2011

Reflectometry using Global Navigation Satellite System's (GNSS) opportunity signals was originally conceived for altimetry [1], but it has been demonstrated today that it can be applied to sea state determination, soil moisture, vegetation, snow monitoring... So far, GPS signals scattered over the Earth's surface have been cross-correlated with a local replica of the transmitted signal (typically the only GPS available: ...

  • Analog-to-Digital Conversion

    This chapter addresses analog-to-digital conversion (ADC) for two different types of applications. The first application, linear ADC, is traditionally encountered in digital signal processing, where the ADC is configured so that a continuous-time, continuous amplitude waveform reconstructed from the ADC outputs closely matches the ADC input. The second and very different application is a digitizing correlator, where the ADC output is cross- correlated with a digitized signal replica. The chapter first provides an overview of ADC and associated automatic gain control (AGC), defining the conversion process and describing the role of gain control and approaches for implementing it. Next, it reviews traditional guidelines for sampling frequency and quantitation steps used in conventional linear digital signal processing. Then, the chapter introduces the concept of the digitizing correlators, and provides results for ADC design for digitizing correlators.

  • Spread Spectrum Systems

    In spread spectrum systems the transmit signal occupies a wider spectrum than required by the symbol rate. Slow and fast Frequency Hopping (FH) changes the carrier frequencies, and can be used for multiple access in synchronized and unsynchronized systems. In Code Division Multiple Access (CDMA), the data sequences are multiplied by spreading sequences with short chip duration, thus increasing the occupied bandwidth by the ï¿¿ï¿¿ï¿¿spreading factorï¿¿ï¿¿ï¿¿. Spreading sequences with suitable crosscorrelation (and autocorrelation) properties allow separation of users: pseudonoise (PN) sequences like maximum- length (m-) sequences, Gold-, and Kasami-sequences; Walsh-Hadamard codes and Orthogonal Variable Spreading Factor (OVSF) codes. In delay-dispersive channels, Rake receivers consisting of multiple correlators (fingers) collect the energy contained in different multipath components. Synchronization of the receivers to the available signals occurs in two steps: acquisition and tracking. CDMA allows universal frequency reuse (i.e., reuse distance one). Inter-user interference (consisting of intra-cell and inter-cell interference) is noise-like. Randomization of inter-cell interference is effected by multiplying the signals in different cells with different scrambling codes. Power control ensures that no single user provides dominant intra-cell interference (in the uplink). Near the cell edge, soft handover ensures good transmission quality through macrodiversity. Multiuser detection (MUD) is based on exploiting the structure of interference to mitigate its effect on the desired signal. Linear MUDs include decorrelating receivers and MMSE receivers. Nonlinear MUDs include the (optimum) multiuser MLSE as well as successive interference cancellation (SIC) and parallel interference cancellation (PIC). Time hopping impulse radio, mostly used in ultrawideband (UWB) communicat ions, represents each symbol by a sequence of pulses. Transmitted-reference signals allow simple receivers.
