在提供高数据速率的无线系统中，对抗和利用无线信道的频率选择性的重要技术之一就是均衡技术。在过去的几十年里，无线系统的发展需要均衡技术的设计和分析。当前趋势以及未来一代的无线系统应该具有非常高的频谱效率，由于高移动性和发射机和/或接收机部分或无信道状态信息的可用性而存在快速时变信道，这规定了MIMO系统。当数据以高比特率在移动无线电信道上传输时，信道脉冲响应可以扩展到许多符号周期，从而导致符号间干扰（ISI）。本文以两发两收天线（2×2 MIMO）为例，分析了平衰落瑞利多径信道上均衡技术的性能，并给出了误码率分析。
One of the important techniques, which can combat and exploit the frequency-selectivity of the wireless channel in providing high data rate wireless systems, lies in the hand of equalization. The wireless systems that is evolved the last few decades necessitates in the design and analysis of equalization techniques. The current trend as well as the future generation of wireless systems is supposed to possess very high spectral efficiency, presence of rapidly time varying channels due to high mobility and the availability of partial or no channel state information at the transmitter and/or receiver which prescribes MIMO systems. When the data is transmitted at high bit rates, over mobile radio channels, the channel impulse response can extend over many symbol periods, which lead to Inter-symbol interference (ISI). This paper analyses the performances of equalization techniques by considering 2 transmit and 2 receive antenna (2×2 MIMO) over a flat fading Rayleigh multipath channel and provides a bit error rate analysis of the same.
