摘要 MIMO(多输入多输出)-OFDM(正交频分复用)技术通过在OFDM传输系统中采用阵列天线实现空间分集,利用时间、频率和空间3种分集技术,使无线系统对噪声、干扰、多径的容限大大增加。在介绍MIMO-OFDM各种技术的基础上,给出其系统模型。MIMO-OFDM技术在提高无线链路的传输速率和可靠性方面具有巨大潜力,并会成为未来宽带无线领域的关键技术。 MIMO - OFDM achieves space diversity through adopting array antenna in OFDM transmission systems. It can greatly increase the containing to noises, interference and many pathway by using the diversity technology of time, frequency and space. The author provides the system model upon the introduction of all kinds of the technology of MIMO-OFDM. MIMO-OFDM has the immense potential to improve transfer speed and security wireless route. It will be the key technique in the future broad-band wireless communications.
