As it is discussed in Chapter 1, power and bandwidth are limited resources in modern communication systems, and the efficient exploitation of these resources invariably involves an increase in complexity. It has become apparent over the past few decades that when there are strict limits on the power and bandwidth resources, the complexity of communication systems still can be increased to obtain efficiencies that are even closer to the theoretical limits.
