摘要
分析了 MIMO 技术的核心空时编码技术,研究了 OFDM 的基本原理,对两发两收和两发一收 MI—MO-OFDM 系统进行了仿真,并分析了系统的 BER 性能,仿真结果显示,两发两收 MIMO-OFDM 系统 BER 性能明显优于两发一收系统,具有较高的实用价值。
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.
