Designing Digital Communication Systems
Introduction
This article is intended to serve as a "road map" for outlining typical steps to be considered in meeting the bandwidth, power, and error-performance requirements of a digital communication system. The criteria for choosing modulation and coding schemes, based on whether a system is bandwidth-limited or power-limited, are reviewed for several system examples, and the article emphasizes the subtle but straightforward relationships that exist when transforming from data bits to channel bits to symbols to chips.
