Performance analysis of efficient and low complexity MIMO-OFDM using STBC and V-BLAST

Abstract

This paper presents the performance of V-BLAST and STBC on MIMO-OFDM.V-BLAST is superior in terms of spectral efficiency and bit error rate. The performance analysis of V-BLAST based multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) system also analyzed with respect to bit error rate per signal to noise ratio (BER/SNR) for various detection techniques i.e. zero forcing (ZF), minimum mean square error (MMSE) and maximum likelihood (ML). A 2×2 MIMO-OFDM system is used for the performance evaluation. The simulation results show that the performance of V-BLAST based detection techniques is superior than to that of conventional methods.
