Abstract

MIMO-OFDM system has been currently recognized as one of the most competitive programs for 4G mobile wireless systems. MIMO-OFDM system can compensate for the lacks of MIMO systems and give play to the advantages of OFDM system. The signal detection technology of MIMO-OFDM system is mainly studied in the paper, including linear detection method of zero forcing (ZF) detection and the minimum mean square error (MMSE) detection, as well as the non-linear detection method of V-BLAST detection, those detection algorithms are simulated based on matlab in different modulation for searching which is the optimal detection algorithm of the channel.
