Performances Simulation of Flat Fading Channels in Mobile Ad Hoc Networks

The bit error rate is an important metric to consider when analysing performance of wireless system. The mobile-to-mobile channels are quite different from fixed-to-mobile channels especially the power spectral density of the Doppler spread. This paper proposes the performances simulation of M2M channel in ad hoc networks context. The simulations are carried out using a realistic channel model and a DQPSK modulation with differential detection. The results show the effect of double mobility degree on bit error rate.
