Wireless channels are becoming more and more important, with the
future development of wireless ad-hoc networks and the integration
of mobile and satellite communications. To this end,
algorithmic detection aspects (involved in the physical layer) will
become fundamental in the design of a communication system.
This book proposes a unified approach to detection for
stochastic channels, with particular attention to wireless
channels. The core idea is to show that the three main criteria of
sequence detection, symbol detection and graph-based detection, can
all be described within a general framework. This implies that a
detection algorithm based on one criterion can be extended to the
other criteria in a systematic manner.
* Presents a detailed analysis of statistical signal detection
for digital signals transmitted over wireless communications
* Provides a unifying framework for different signal detection
algorithms, such as sequence detection, symbol detection and
graph-based detection, important for the design of modern digital
receivers operating over mobile channels
* Features the hot topic of graph-based detection
Detection Algorithms for Wireless Communications
represents a novel contribution with respect to the current
literature, with a unique focus on detection algorithms, as such it
will prove invaluable to researchers working in academia and
industry and in the field of wireless communications, as well as
postgraduate students attending advanced courses on mobile
communications.
