Space-Time Turbo Codes With Adaptive Beamforming for MIMO-OFDM : Performance Analysis & Evaluation
This paper proposes a MIMO-OFDM system with adaptive beamforming algorithm for smart antenna. Performance analysis of the combined scheme is presented using optimum turbo codes with transmit diversity on AWGN channel. The performance of the proposed system is tested for various modulation techniques such as BPSK, QPSK, 16-PSK& 256-PSK.Simulation results demonstrate that the proposed system has good ability of suppressing interference and significantly improves the Bit-Error Rate (BER).Experimental results show that an adaptive beamforming gives the optimum performance on AWGN channels.
