Diversity gain for rician and Rayleigh environments in reverberation chamber

Reverberation chamber is used to characterize the diversity gain based on its properties of diffuse field. First, we isolate the effects on diversity gain due to different factors, resulting in a composite power imbalance. Then, we describe the power correlation as a function of the complex correlation when the K-factors on different channels are not identical. By using Monte Carlo simulations, we estimate the maximum diversity gains for different configurations (i.e., different levels of K-factor, power imbalances, complex correlations). We measure the diversity gain when changing the correlation between the received signals (at antenna array) and when the unstirred power level at reception changes. Then, we compare these results with those issued from statistical simulations.
