Abstract :
Multiple-input-multiple-output (MIMO) systems and reverberation chambers (RCs) have joined roads in recent years. This is due to the recently developed ability of RCs to produce a controllable environment that reduces the cost, time, and effort of evaluating the performance of MIMO handset antennas. This letter explores one of these new capabilities to evaluate systems that use true polarization diversity (TPD). Through a novel post-processing hybrid tool for the transformation of a Rayleigh-fading environment into a Rician one, the performance of TPD systems for different Rician fading is shown. Different arrays will be used for the purposes of comparison. This investigation demonstrates that TPD improves traditional orthogonal polarization also for Rician fading.
