Abstract

Matched chirp modulation (MCM) is an improved version of chirp modulation (CM) in which the frequency sweep rate is matched to the dispersion parameters of the communication channel. It is an attractive constant-envelope digital modulation technique for adaptive transmission over dispersive communication channels. The performance of the optimum noncoherent (NC) and partially coherent (PC) receivers for MCM is analyzed and evaluated. In particular, the optimum value of the time-bandwidth product is evaluated, and the probability of error is calculated for the optimum NC and PC receivers
