Adaptive WCDMA (P1)

ADAPTIVE COMMUNICATIONS AND THE BOOK LAYOUT In order to justify the content of the book and to make suggestions on how the book should be studied, we start with the generic block diagram of a digital communication system shown in Figure 1.1. The standard building blocks, information source, source encoder, encryptor, channel encoder and data modulator are used to produce a narrowband signal, for example, binary phase shift keying (BPSK), quaternary phase shift keying (QPSK) or M-ary quadrature amplitude modulation MQAM carrying information content. The spreading of the signal spectra is obtained by real or complex multiplication of the narrowband...
