| Popis: | Although the widely linear minimum mean-square error (WLMMSE) receiver has been widely applied in multiple-input-multiple-output (MIMO) systems, there has been no theoretical analysis to quantify its distribution of signal-to-interference-plus-noise ratio (SINR) in arbitrary fading environments. In this paper, the closed-from expression of SINR at the output of the WLMMSE detection is presented, which, in its essence, can be interpreted as the sum of a series of gamma distributed random variables. The general probability density function of SINR is derived for the first time, which is explicitly expressed in terms of the confluent Lauricella hypergeometric function. Simulations on MIMO transmission systems over Rayleigh fading channels support the analytic results. |
