Abstract

Spectral characteristics of signals and bit error probability of transmission systems are analytically evaluated with reference to full response CPFSK systems with rectangular modulation pulse shaping and limiter-discriminator detection, applied on a typical cellular radio network. The analysis is carried out in the case of four-level signals, in the presence of transmission nonlinearities and cochannel and adjacent channel interferences. The results obtained show that the spectral compactness cannot be assumed as a good index of a bandwidth-efficient modulation system. Moreover, in some significant cases, which differ because of vehicular locations, channel spacing and modulation parameters, they indicate the signal-to-noise ratios necessary at the receiver input to guarantee a fixed bit error probability, in both the base-to-mobile and mobile-to-base transmissions.
