摘要

我们给出了与正交频分复用(OFDM)结合使用的空时编码系统的多径信道估计和检测结果。介绍了一种基于期望最大化(EM)的算法，该算法对多径信道延迟曲线变化具有更强的鲁棒性，并且与最近提出的替代算法相比，在类似或更好的性能下可以更有效地实现。

Some results on channel estimation and detection for space-time OFDM systems

We present results on multipath channel estimation and detection for space-time coded systems used in conjunction with orthogonal frequency-division multiplexing (OFDM). An expectation-maximization (EM) based algorithm is introduced and is shown to be more robust to multipath channel delay profile variations and can be implemented more efficiently compared to a recently proposed alternative algorithm at similar or better performance.
