Enhanced MIMO Transmission Scheme for MB-OFDM System with Spatial Mode Selection
The transmission of huge multimedia data and software components has been increased in recent years in home and this explosive growth of wireless communication is creating demand for high speed, reliable, and spectrally efficient communication in home networking environments. Therefore, dynamic data transmission with proposed scheme for MB-OFDM system is considered in this paper. The proposed scheme is investigated for the most suitable adaptation in home networking environments. And this scheme includes STBC, VBLAST, and STBC-VBLAST in all. By properly selecting their MIMO schemes agreeable to estimated SNR, the proposed scheme has the advantage of each technique; diversity gain or high transmission rate relative to general scheme.
