On performance analysis for signaling on correlated fading channels

A general approach is presented for analyzing the performance of digital signaling with multichannel reception on correlated fading channels. The approach is based on: i) exploiting the complex Gaussian model for the joint distribution of the fading on the multiple channels; and ii) applying recent results on the unified performance analysis of digital signaling on fading channels using alternative representations of the Q(·) and related functions. Numerical results that illustrate the effect of correlation on the diversity gain from multichannel reception are also presented.
