摘要：
The channel capacity of dual-branch MRC (maximal ratio combining) diversity system over correlated waveform intensity, which is characterized as correlated-Nakagami-m fading (the power is naturally modeled as the correlated-Gamma statistics), is evaluated in this paper. The formulas of channel capacity performance are provided with a pdf (probability density function)-based approach. The pdf of sum of Gamma variates based on the representation of a single gamma series is adopted in the paper. The corresponding expressions of the pdf with the Rayleigh distribution are able to be obtained as a special case of Nakagami-m fading. Finally, the numerical examples are presented and discussed for illustrating the purpose of validating the accuracy of the channel capacity equations derived in this paper.
