Wireless digital communication: a view based on three lessons learned

Abstract

The implications of Shannon's information theory for personal communication network (PCN) design are outlined. Examples of improvements in satellite communication, magnetic recording, and modem technologies that have increasingly approached information-theoretic limits are given. The emphasis is on the application of Shannon's work to control of four types of interference: multi-user, multiple cell, multipath, and multiple media. Code-division multiple access (CDMA), time-division multiple access (TDMA), and frequency-division multiple access (FDMA) techniques in personal communications are compared.
