Digital communication receivers P4

Receiver Structure for PAM Signals In this chapter we first discuss the main building blocks of a digital receiver (Section 4.1). The discussion is intended as an introduction to get a qualitative understanding of the design issues involved. In Section 4.2 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 to be discussed in Section 4.3. Here we systematically derive the optimum receiver based on the maximum-likelihood criterion, The essential feature of...
