Recent studies have shown that the combination of two enabling technologies, multi-input multi-output (MIMO) and orthogonal frequency division multiplexing (OFDM), is the most promising wireless access scheme for the fourth-generation (4G) mobile communication systems. Channel estimation plays a key role in the future 4G systems that are based on the MIMO-OFDM technology, since the system performance largely depends on the channel state information (CSI) of the time-varying wireless environment.

最近的研究表明，多输入多输出（MIMO）和正交频分复用（OFDM）两种使能技术的组合是第四代（4G）移动通信系统最有前途的无线接入方案。信道估计在基于MIMO-OFDM技术的未来4G系统中起着关键作用，因为系统性能很大程度上取决于时变无线环境的信道状态信息（CSI）。
