Book Description
This SpringerBrief investigates the performance of semi-blind independent component analysis (ICA) based equalization and carrier frequency offset estimation approaches (CFO) for a number of orthogonal frequency division multiplexing (OFDM) based wireless communication systems. It provides a comprehensive overview of the challenges of channel equalization and frequency synchronization for different wireless systems. The authors present the wireless communication channel and system models. Key existing CFO estimation methods are reviewed, along with a number of the training based and non-training based (blind) channel estimation methods. This is followed by a study of ICA and its applications to OFDM-based wireless communication systems. Later chapters provide a detailed description of recent research on semi-blind CFO estimation and ICA based equalization approaches for various wireless communication systems including multiple-input multiple-output (MIMO) OFDM and coordinated multipoint (CoMP) systems. Semi-blind CFO estimation and equalization structures provide a spectrum-efficient and high-performance solution for high speed wireless communications. This book is suitable for postgraduate students, researchers or professionals in the area of wireless communications.

Book Description
Broadband wireless communication requires fast and reliable synchronization and channel estimation with low overhead and computation complexity. In this work, we address the above issue by two aspects. First, we develop training signal design for not only achieving low complexity reliable receiver processing algorithms, but also improving the theoretical limit. Second, we develop low complexity high performance receiver algorithms for both single user and multiuser system. We first investigate the optimal periodic preamble design for frequency offset estimation over frequency-selective fading channels by minimizing the average Cramer-Rao bound (CRB). The proposed design includes the optimal sequence structure design and the optimal signal design, and brings new dimensions into the existing theory of the training signal designs for frequency offset estimation. To track the channel variations as well as the phase shift, data-pilot multiplexing scheme is commonly used in OFDM (orthogonal frequency division multiplex) systems. The two performance metrics which are not jointly incorporated yet in the existing data-pilot multiplexing scheme design are the number of data tones transmitted over one OFDM symbol (data throughput) and the channel response and phase estimation performance. In this work, we propose two multiplexing schemes which significantly improve the estimation performance with low data throughput sacrifice, resulting in a substantial performance improvement over current pilot-data multiplexed schemes. In the uplink of OFDMA (orthogonal frequency division multiple access) systems, synchronization and channel estimation problems become more challenging since multiuser, multi-dimension parameters rather than single user parameters issue have to be estimated. The existing techniques have one or more of the following unfavorable requirements: high computation complexity, loss of frequency diversity, and performance sensitivity to the number of subscribe stations. To address the above drawbacks, we propose several training designs as well as the corresponding estimators for OFDMA uplink in this thesis, yielding robust low complexity estimators with enhanced performance.

Book Description
The issue of channel estimation in wireless communication systems is very crucial for coherent detection of the transmitted signal at the receiver end of the systems.Different techniques have been proposed in many books in a bid to obtain near-optimum channel state information for wireless communication systems. In this book, these techniques are reviewed and efficient channel estimation techniques for employment in Single Input Single Output (SISO) wireless communication systems, Single Input Single Output - Orthogonal Frequency Division Multiplexing (SISO-OFDM) Systems and Multiple Input Multiple Output - Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems are proposed. The review of various channel estimation techniques and the proposed techniques presented in this book should be of great interest to both undergraduate and postgraduate students in the general field of telecommunication engineering systems. The professional engineers in the field of telecommunication engineering will also find this book useful in designing new communication equipments for wireless communication systems.

Book Description
Adaptive techniques play a key role in modern wireless communication systems. The concept of adaptation is emphasized in the Adaptation in Wireless Communications Series through a unified framework across all layers of the wireless protocol stack ranging from the physical layer to the application layer, and from cellular systems to next-generation wireless networks. This specific volume, Adaptive Signal Processing in Wireless Communications is devoted to adaptation in the physical layer. It gives an in-depth survey of adaptive signal processing techniques used in current and future generations of wireless communication systems. Featuring the work of leading international experts, it covers adaptive channel modeling, identification and equalization, adaptive modulation and coding, adaptive multiple-input-multiple-output (MIMO) systems, and cooperative diversity. It also addresses other important aspects of adaptation in wireless communications such as hardware implementation, reconfigurable processing, and cognitive radio. A second volume in the series, Adaptation and Cross-layer Design in Wireless Networks(cat no.46039) is devoted to adaptation in the data link, network, and application layers.
