Abstract

Closed-form analytical symbol error rate expressions are derived for a MIMO link with linear matrix transmits prefilter and minimum mean squared error receiver in a Rayleigh fading environment. Specifically, using a well-known simplified MIMO channel model, where correlation between the transmit and receive antenna elements is modeled independently, we present exact expressions for vanishing fading correlation as well as the case of correlation between the transmit antenna elements with long-term eigenmode transmission for arbitrary array sizes. Furthermore, exact results are given for a 2×2 system with fading correlation at both transmitter and receiver. High SNR approximations allow a simple quantification of the influence of fading correlation. The accuracy of the analysis is demonstrated via Monte-Carlo simulations.
