The role of digital signal processing in personal communications networks

Digital signal processors (DSPs) are playing a major role in personal communications networks (PCNs). DSPs impact not only the new digital networks but also analog systems. The reasons for this impact are the advances in integrated circuit (IC) process technology, the manipulation of signals in the digital domain, and the advantages of selectively using programmable solutions and hard wired solutions. The authors discuss these advantages along with examples.<
