Abstract： Multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) is the foremost space interface for 4G and 5G broadband wireless communication. MIMO can transmit diverse signals over multiple antennas and OFDM can divide a radio channel into a huge number of closely spaced sub channels to afford more reliable communications at high speed. Research show that MIMO can be used with other well-liked wireless interfaces such as time division multiple access (TDMA) and code division multiple access (CDMA), the amalgamation of MIMO and OFDM is most realistic at higher data rates. It is conclude that by using different turbo coding rate, we are getting improved bit error rate (BER).
Key words： time division multiple access （TDMA）； code division multiple access （CDMA）； multi-input multi-output （MIMO）； orthogonal frequency division multiplexing （OFDM）

摘 要: 多输入多输出正交频分复用（MIMO-OFDM）是4G 和5宽带无线通信中最重要的空间接口。 MIMO 可通过多路天线传输多种信号， OFDM可将一条无线通道分隔成空间非常接近的大量子通道， 从而提供更可靠的高速通信。 研究结果表明， MIMO还可以和其他接口联合使用， 如时分多址（TDMA）和码分多址（CDMA）。 MIMO and OFDM 的结合对高速数据传输是最实际的应用。 利用不同的turbo编码率, 误码率（BER）得到了改善。
