Zf And Mmse Equalizer

Zf And Mmse Equalizer



5/18/2012  · Abstract: This paper presents an in-depth analysis of the zero forcing (ZF) and minimum mean squared error (MMSE) equalizers applied to wireless multi-input multi-output (MIMO) systems with no fewer receive than transmit antennas. In spite of much prior work on this subject, we reveal several new and surprising analytical results in terms of output signal-to.


that ZF and MMSE are asymptotically equivalent at high SNR, we show that the output SNR of the MMSE equalizer (conditioned on the channel realization) is ‰mmse = ‰ zf + ·snr, where ‰zf is the output SNR of the ZF equalizer, and that the gap ·snr is statistically independent of ‰zf and is a non-decreasing function of input SNR.


Contrary to the common perception that ZF and MMSE are asymptotically equivalent at high SNR, we show that the output SNR of the MMSE equalizer (conditioned on the channel realization) is ? mmse = ? zf +? ssr snr, where ? zf is the output SNR of the ZF equalizer and that the gap ? ssr snr is statistically independent of ? zf and is a nondecreasing function of input SNR.

From the simulation we realize that the MMSE has better results than the ZF equalizer in case of single antennas configuration SISO and in MIMO, but the ZF equalization has the advantage in case of SIMO, in MIMO case the three equalizers are compared and the results shows that the SSD equalizer has the advantage over the ZF and the MMSE in OLSM or LTE transmission.
