BER Performance of Alamouti with VBLAST Detection Schemes over MIMO System

Multiple-Input Multiple-Output (MIMO) systems as a means to combat fading in wireless channels. MIMO allows higher throughput, diversity gain and interference reduction. In this paper, we analyze the Bit Error Rate (BER) performance of the Alamouti Space Time Block Code with V-BLAST (Vertical Bell Laboratories Layered Space-Time) over MIMO system. Basic idea in this scheme is to improve the BER performance of systems. V-BLAST algorithm offers highly better error performance than conventional linear receivers and still has low complexity. The simulated results are based on different modulations, such as BPSK, 4-QAM and 16-QAM over Rayleigh fading channels. DOI: 10.17762/ijritcc2321-8169.150511
