摘要

本文提出了一种带均衡器的MIMO通信信道预滤波器设计方法。在频域设计预滤波器，使信道更容易均衡。我们应用信道频率响应的奇异值分解(SVD)来设计预滤波器。该预滤波器在高信噪比(SNR)条件下实现了性能提升，同时保持了低信噪比条件下的性能。我们还展示了发射机分集的优势。

Prefilter design using the singular value decomposition for MIMO equalization

This paper describes a new prefilter design method for MIMO communication channels with equalizers. The prefilter is designed in the frequency domain to make the channel easier to equalize. We apply the singular value decomposition (SVD) of the channel frequency response to design the prefilter. The new prefilter achieves a performance improvement at high signal to noise ratio (SNR) while keeping the performance at low SNR. We also show the advantage of transmitter diversity.
