Performance Analysis Of A Digital Mobile Radio Cellular System In Presence Of Co-Channel Interference, Thermal And Impulsive Noise

Abstract

The performance of a mobile cellular radio network is analyzed in the presence of co-channel interference, Gaussian noise and narrow-band impulsive noise (Middleton's class A noise) using differential phase shift keying (DPSK) rnodulacion. The performance is measured in terms of bit error probability and spectrum efficiency. The influence of reuse distance, i.e. cluster size, and traffic intensity on the performance parameters has been investigated. The mobile environment is considered as (fast) Rayleigh fading channel. The UHF groundwave propagation law is introduced by considering the local mean power to be inversely propotional to the fourth power of propagation distance.
