<b>MIMO OFDM s BER and Design Performance for Wireless Broadband Communications</b> To get high data rates, speed and immediate amplify in range and reliability without consuming more radio frequency require MIMO OFDM for wireless broadband communication. In this paper, we investigate the performance of MIMO OFDM using diverse modulation schemes are used to encode and decode the data stream in wireless communication over AWGN channel for the indefinite transmitter and known receiver. In exacting we relate MIMO detection methods based on V BLAST Vertical Bells Lab Layered Space Time planning to develop spectral efficiency.
