Our goal in this chapter is to review the most popular digital modulation techniques, specifically, those that are most often addressed in the literature, and discuss their transmitted signal form as well as their detection over the additive white Gaussian noise (AWGN) channel. In all cases, we shall limit our consideration to receivers that implement the maximum a posteriori (MAP) decision rule (maximum-likelihood (ML) for equiprobable signal hypotheses) and as such are optimum from the standpoint of minimizing error probability. Emphasis will be placed on those modulations that might be used in applications where the channel exhibits multipath fading.
