Summary

In this chapter we first discuss the main building blocks of a digital receiver. The discussion is intended as an introduction to get a qualitative understanding of the design issues involved. Here we are concerned with the question under what conditions the samples of the received signal contain the entire information on the continuous-time signal. The samples obtained under such conditions provide so-called sufficient statistics for the digital receiver are discussed. We systematically derive the optimum receiver based on the maximum-likelihood criterion. The essential feature of our approach is that the receiver structure is the outcome of a mathematical optimization problem.
