Abstract
This paper presents the comparison of probability of bit error rate between the zero forcing (ZF) and minimum mean squared error (MMSE) equalizers applied to wireless multi-input multi-output (MIMO) systems. Contrary to the common perception that ZF and MMSE are asymptotically equivalent at high SNR, it shows that the output SNR of the MMSE equalizer (conditioned on the channel realization) is ρmmse = ρZf + ηSNR , where ρZf is the output SNR of the ZF equalizer, and that the gap ηSNR is statistically independent of ρZf and is a non-decreasing function of input SNR. Furthermore, as SNR → ∞, ηSNR converges with probability one to a scaled ƒ random variable. It is also shown that at the output of the MMSE equalizer, the Interference-to-noise ratio (INR) is tightly upper bounded by .
