Performance limits of coded multilevel differential PSK (MDPSK) in multipath Rayleigh fading channels are described. The simple “Gaussian metric” is assumed for reasons for practicality even though it is not the maximum likelihood. Channel cutoff rate R0of MDPSK is analyzed based on the metric. Account is taken of additive white Gaussian noise (AWGN), cochannel interference, and multipath channel delay spread. For the analysis of the spectrum efficiency of a cellular mobile radio system employing coded MDPSK, its service area is defined as the area in which, with a bit rate of R information bit/symbol (R ≦ R0), reliable communications are possible. Three optimal information bit rates are determined from the channel cutoff rate to minimize the required average signal energy per information bit-to-noise power spectral density ratio (Eb/N0), to maximize the tolerable rms delay spread τrmsand to maximize the spectrum efficiency.
