Abstract

The performance of spatial multiplexing-based multiple-input multiple output (MIMO) systems using zero forcing (ZF) detector in frequency selective fading channels is analyzed in this paper. The approximation of a linear combination of Wishart matrices is used to derive the probability density function (p.d.f.) of output signal-to-noise ratio (SNR) expression. Analytical error rate expressions for the system are obtained with the assumption that inter-path interference is omitted. Simulations are carried out to evaluate the analytical results. We relate the diversity order of frequency selective fading channels with the multipath power delay profile.
