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 ( ) and related functions. Numerical results that illustrate the effect of correlation on the diversity gain from multichannel reception are also presented.
