Abstract:
Multiple input Multiple Output (MIMO) systems in conjunction with orthogonal frequency division multiplexing (OFDM) are extensively used in modern communication systems in order to improve throughput and robustness in multipath fading environments. In this paper to enhance the order of spatial diversity in presence of deteriorative fading correlations we proposed Least Mean Square (LMS) and Recursive Least Square (RLS) adaptive Algorithm. This paper uses V-BLAST-ZF detection for MIMO-OFDM receiver. The performance measures used in this paper is BER and SNR. This study shows that the BER performance of MIMO-OFDM system with beamforming is better than system without using beamforming. This paper also shows the performance for the adaptive algorithm LMS and RLS, and concludes that RLS algorithm significantly outperforms over the LMS.
