论文摘要
在多输入的多输出通信中，频道估计对于保持基站和用户的步骤至关重要。本文提出了一种基于PCA的新型主要组件分析 - 通道估计方法，用于MIMO正交频分多路复用系统。首先使用最小二乘方法估算通道频率响应，然后PCA仅用于过滤通道脉冲响应的较高奇异组件，然后将其转换回频域。将所提出的方法与MMSE（根据位错误率与EB/N0）的MMSE（最小平方误差估计）进行了比较。
In multiple-input multiple-output communications, channel estimation is paramount to keep base stations and users on track. This paper proposes a novel PCA-based-principal component analysis-channel estimation approach for MIMO orthogonal frequency division multiplexing systems. The channel frequency response is firstly estimated with the least squares method, and then PCA is used to filter only the higher singular components of the channel impulse response, which is then converted back to the frequency domain. The proposed approach is compared with the MMSE, the minimum mean square error estimation, in terms of bit error rate versus Eb/N0.
