Distributions of multiuser-MIMO under correlated generalised-Rayleigh fading

Under even degrees of freedom, new single-integral and infinite-summation selection combiner output signal-to-noise ratio and signal-to-interference-and-noise ratio distributions of multivariate equally-correlated generalised-Rayleigh fading for multiuser-multiple-input-multiple-output (MU-MIMO) systems are obtained. The proposed findings can be employed to approximate intractable distributions of multivariate exponentially-correlated Rician fading. An average bit error rate of the differential binary phase-shift keying scheme for MIMO networks is derived using the new distributions, showing their efficiency for network assessment.
