Abstract :
The authors deal with the simulation and the analysis of a Suzuki process. This stochastic process can be considered to be a model for the random fluctuations of the envelope of the received signal in land mobile radio transmission systems. Digital speech transmission over such a channel is disturbed by these random fluctuations, in particular during the fading periods. Therefore, the knowledge of the frequency of the fades and the distribution of their duration is of special interest. The simulation system is used to determine these quantities experimentally. Recent results are presented, and the average number of fades is derived theoretically
