| Abstract: | Space-Time Coding technology, one of the most important technologies in MI- MO was mainly analyzed, and the basic theory of OFDM was studied. At last, the performance of 2Tx-2Rx and 2Tx-lRx MIMO-OFDM system was analyzed by simulation. The BER performance of 2Tx-2Rx MIMO-OFDM system was much better than 2Tx-1Rx system, and this system was available to the practial use. |
