A signal-space analysis of spatial self-interference isolation for full-duplex wireless

The challenge of full-duplex wireless communication is self-interference received directly from the transmit antennas and backscattered from nearby objects. Spatial isolation of the receive antennas from the transmit antennas can mitigate self-interference, but may cause the spatial resources of the channel to be under-utilized, sacrificing spatial multiplexing performance. We present an analysis of spatial isolation of self-interference for full-duplex base ...

  • Dynamic Planning in Green Networks

    This chapter investigates operation of green wireless networks by using a dynamic planning approach. These approaches are the major focus of the chapter. The chapter presents optimal energy¿¿?efficient and QoS¿¿?aware dynamic cell¿¿?zooming and BS¿¿?switching policies for dense small¿¿?cell deployment subject to constraints on user data rate requirements and outage probability. It dicusses a dynamic planning approach that can capture and balance the trade¿¿?off in energy efficiency between network operators (in the downlink) and mobile users (in the uplink). Several works have addressed energy¿¿?efficient cell¿¿?zooming mechanisms and sleep policies for heterogeneous networks with dense small¿¿?cell deployment. The chapter presents a dynamic planning approach to optimally associate users to access nodes (pico and macro BSs) by adjusting the coverage area of these BSs. It talks about an analytical model for optimizing the cell size in a dense macro¿¿?pico heterogeneous network to minimize energy consumption while maintaining the end user quality of service.

  • Galileo

    Galileo comprises a space segment, a ground segment, and a user segment. The fully deployed system consists of a minimum of 24 satellites and extensive worldwide ground infrastructure. This chapter provides a brief history of Galileo and provides detailed characteristics of Galileo signals. Galileo was designed to offer four navigation services as well as a search and rescue service. The Open Service (OS) provides signals for timing and positioning to anyone, free of user charges. The Safety-of-Life service (SoL) had originally been developed to provide assured integrity signals for timing and positioning. The GMS uses a global network of Galileo Sensor Stations (GSS) to monitor Galileo downlink signals for two purposes: measurement of orbit and clock offsets from each satellite, and monitoring the integrity of each signal. The chapter summarizes the frequency plan using what has become Galileo's notation.

  • Reception of Spread Spectrum Signals in AWGN Channels

    In this chapter we review the fundamental concepts of the reception of signals transmitted over AWGN channels, first of all the reception of wideband signals transmitted over multiple access channels with additive white Gaussian noise.

We study coherent reception of uplink and downlink transmitted DS CDMA signals, differential phase-shift keying, and reception of FH SS signals.

  • Green Multi¿¿?homing Approach

    This chapter presents the heterogeneous wireless communication medium and discusses the potentials of multi¿¿?homing approach in green communications. It focuses on several challenging issues pertaining to the design and implementation of the green multi¿¿?homing approach. The heterogeneous wireless access medium exhibits great potential in improving energy efficiency while satisfying the QoS of mobile users. Multi¿¿?homing services can aggregate bandwidth from different networks, enable better mobility support and reduce energy consumption for mobile users and network operators. In addition to exploiting different channel conditions and path losses among MTs and BSs/APs of different networks, the available bandwidth and operating frequency bands at different networks can further enhance energy efficiency. In joint bandwidth and power allocation for uplink and downlink communications in a heterogeneous networking setting, there are many challenging technical issues including fairness in energy efficiency among MTs, decentralized implementation with reduced signalling overhead, in¿¿?device coexistence (IDC) interference management and implementation complexity.

  • WiMAX/IEEE 802.16

    This chapter gives an overview of WiMAX (Worldwide Interoperability for Microwave Access). A Wimax system consists of access service network (ASN) and internet-based connectivity service network (CSN). It specifies both a FDD mode when operating in paired spectrum, and a TDD mode for upaired spectrum. Multiple access capability is achieved by OFDMA, in particular different users are assigned different subcarriers. We first review the physical layer. Wimax uses OFDM (with cyclic prefix) with adaptive modulation and coding for both the uplink and the downlink. For error correction coding, convolutional codes and turbo codes are foreseen; further error correction is achieved by hybrid ARQ (HARQ) with chase combining or incremental redundancy. We then turn to the logical channels and physical channels (time/frequency resources). The time axis is divided into zones, frames, and subframes. In addition to the data bursts for the separate users, a frame contains preambles and control signaling (DL and UL-MAP, Frame Control Header FCH), and the ranging subchannel. Various schemes exist for subcarrier permutation, i.e., assigning data to the time/frequency resources (called subchannels and tiles, i.e., subcarriers or groups of subcarriers). Different types of permutations are defined for use in different zones: the PUSC (partial use of subcarriers), TUSC (tiled use of subcarriers), FUSC (full use of subcarriers), and AMC (Adaptive modulation and coding). We then describe multiple antenna techniques in Wimax. For space-time coding, Alamouti, antenna selection, antenna cycling, and/or beamforming is used. Spatial multiplexing is either open-loop, or closed-loop (precoding). We finally discuss link control, including establishing of a connection (including scanning, synchronization, initial ranging), scheduling and resource request, quality of service (QoS) control, power control, handover, and mobility support.

  • Non-orthogonal Multi-User Superposition and Shared Access

    This chapter addresses major technology aspects of non-orthogonal multi-user superposition transmission and shared access. The chapter describes key techniques: low-density spreading (LDS), sparse-code multiple access (SCMA), multi-user shared access (MUSA) and pattern-defined multiple access (PDMA), together with simulation results. For spectral efficiency improvement purposes, a macro-coverage scenario is the suitable deployment environment for non-orthogonal multi-user transmission/access. Deploying non-orthogonal multi- user schemes in a macro setting can help to get both benefits of both of the technologies that will play an important role in significantly boosting the system capacity. The multiple access mechanism in the uplink of IS-95, code division multiple access (CDMA)2000 and Universal Mobile Terrestrial Services (UMTS) is indeed non-orthogonal. One of the key scenarios for downlink non- orthogonal multi-user transmission is mobile broadband (MBB), in which the target is to maximize the downlink system capacity. Roughly, the schemes can be divided into two groups: direct superposition without Gray mapping restriction and superposition with Gray mapping.

  • Multi¿¿?homing for a Green Downlink

    In a heterogeneous wireless medium, downlink multi¿¿?homing radio resource allocation can save power for network operators. In this context, two application scenarios can be distinguished. In the first scenario, the MT aggregates the offered radio resources from different networks to support a single (data hungry) application, while in the second scenario, the MT runs different applications using the radio resources assigned to different radio interfaces. This chapter discusses the challenging issues associated with each application scenario. It presents two downlink radio resource allocation mechanisms that address research issues for the two application scenarios. The downlink green communication problem is formulated as an asymmetric Nash bargain game to jointly allocate radio resources (bandwidth and power) from different networks to a set of MTs with multi¿¿?homing capabilities. The chapter also presents a minimum power consumption radio resource allocation algorithm for LTE/WiFi networks that takes into account the mutual IDC interference between LTE and WiFi.
