Performance of Microcellular Mobile Radio in a Cochannel Interference, Natural, and Man-Made Noise Environment

Abstract

A model is developed for performance analysis of a microcellular digital mobile radio system with Rayleigh-faded cochannel interference, Gaussian noise, and narrow-band impulsive noise (Middleton’s Class A noise) using the differential phase shift keying modulation (DPSK) technique. The desired signal has been assumed to be Rician faded. The effects of selection diversity on the performance have also been investigated and compared to the nondiversity case. The performance is measured in terms of bit error probability and spectrum efficiency. The influence of reuse distance, i.e., cluster size, traffic intensity, i.e., blocking probability, impulsive index, Rician parameter, and turning point of the dual path loss law characteristic of microcells on the performance parameters have been investigated in detail. © 1993 IEEE
