BER Analysis Of IEEE802.11n MIMO System Using MMSE And ZF Detectors

Abstract With the increasing demand of higher data rate for telecommunication the IEEE802.11n standard was constituted in 2009. The most important character of the standard is MIMO-OFDM which not only improves the throughput but also the spectrum efficiency and channel capacity. And in wireless communication the role of MIMO detectors plays an important part to remove inter-symbol interference ISI caused by multipath fading channel. In this paper the BER performance of IEEE 802.11n for 3x2 4x2 and 4x3 antennas are compared using MMSE and ZF detectors in Matlab Simulink.
