Description
Summary:An adaptive modulation and coding (AMC) and adaptive antenna grouping (AAG) architecture for multi-input multi-output orthogonal frequency-division multiplexed (MIMO- OFDM) system was proposed to effectively eliminate or resist various fading in wireless channels and to offer best tradeoff between transmission reliability and capacity. This combining scheme is not only adaptively to modulate to transmit more information over subcarriers but also adaptively to find the optimal STC/SM grouping scheme according to the estimated SNR. The simulation shows that the BER and throughput performance of the AMC and AAG MIMO-OFDM system outperform the conventional MIMO-OFDM and the AMC MIMO-OFDM system.
