Description:

This book is a result of the recent rapid advances in two related technologies: communications
and computers. Over the past few decades, communication systems
have increased in complexity to the point where system design and performance
analysis can no longer be conducted without a significant level of computer support.
Many of the communication systems of fifty years ago were either power or
noise limited. A significant degrading effect in many of these systems was thermal
noise, which was modeled using the additive Gaussian noise channel. Many modern
communication systems, however, such as the wireless cellular system, operate in
environments that are interference and bandwidth limited. In addition, the desire
for wideband channels and miniature components pushes transmission frequencies
into the gigahertz range, where propagation characteristics are more complicated
and multipath-induced fading is a common problem. In order to combat these effects,
complex receiver structures, such as those using complicated synchronization
structures, demodulators and symbol estimators, and RAKE processors, are often
used. Many of these systems are not analytically tractable using non-computer
based techniques, and simulation is often necessary for the design and analysis of
these systems.
