Abstract :
In this contribution. we propose a novel space-frequency block coded adaptive modulated OFDM (SFBC-AOFDM) scheme to provide high data rate and high spectrum efficiency, this scheme is very effective to combat last lading anyway. Its robustness to frequency-selective fading could be adjusted by changing the SFBC coding size and adaptation unit. In this scheme, we extend the application of adaptive modulation into a MIMO-OFDM system in a simple way. Furthermore, a novel SFBC detection algorithm is proposed to reduce complexity for high order QAM employments. We simulate for SFBC-AOFDM with various MIMO settings and analyse the performance of both BCR and transmission efficiency.
