Abstract :
The gain of different diversity techniques that reduce the effects of amplitude and phase fluctuations in radio transmission systems depends on the correlation between the signals in various diversity channels. This paper presents a new approach for the prediction of the envelope correlation coefficient which is the term of interest for combining techniques with phase synchronization. It is based on the results of a deterministic 3D wave propagation model and on the assumption of ergodicity
