The bit error probability is derived for a mobile cellular radio network in the presence of co‐channel interference, Gaussian noise and narrow‐band impulsive noise (Middleton's class A noise) using DPSK (differential phase shift keying) modulation and 4‐QAM (quadrature amplitude modulation). The spectrum efficiency of the mobile radio system is also evaluated. The influence of reuse distance, i.e. cluster size, and traffic intensity on the performance parameters is investigated. The mobile environment is considered as a (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 the propagation distance. It is found that the bit error probability is more vulnerable to Gaussian white noise than to narrow‐band impulsive noise.
