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
Wireless communications is the fastest growing segment of communication technologies. In a wireless communication system, the inter-symbol interference (ISI) is a linear distortion which causes decision errors at the receiver. The equalizer is required to remove the ISI. In the past decade, the blind channel equalization has been a popular research topic in the area of wireless communication. A particular class of blind equalization approaches is based on the second order statistics (SOS) of the received signals. Within this framework, subspace methods exploit the orthogonality between the signal and noise subspaces in order to identify the channel characteristics so that the equalizer can be constructed.This thesis investigates a new equalization algorithm for the time-varying (TV) channel under the single-input multiple-output (SIMO) framework. The TV channel is decomposed using arbitrary basis functions associated with time variable properties of the channels...

Book Description
This book contains revised contributions by the speakers of the 1st IEEE Workshop on Wireless Communication Circuits and Systems, held in Lucerne, Switzerland, from June 22-24, 1998. The aim of the workshop was to demonstrate the vast expertise of the CAS Society in the area of circuit and system design to the rapidly growing field of wireless communications. The workshop combined presentations by invited experts from academia and industry with panel and informal discussions. The following topics were covered: RF System Integration (single-chip systems, CMOS RF circuits), RF Front-End Circuits (CMOS RF oscillators, broadband design techniques), Wideband Conversion for Software Radio (A/D conversion issues, wideband sub-sampling, low-spurious A/D conversion), Process Technologies for Future RF Systems (Si, SiGe, GaAs, CMOS, packaging technologies), DSP for Wireless Communications (DSP algorithms, fixed-point systems, DSP for baseband applications), Blind Channel Equalization (adaptive interference suppression, design techniques, channel estimation). A carefully selected combination of tutorial-like papers as well as papers on specialized and advanced topics is included. Thus, newcomers to the field of wireless communications will benefit from the overview of emerging technologies in circuits and systems, and specialists will benefit from the thought-provoking details presented in this book.
