摘要
Wiener filter is the best channel interpolation method in terms of minimizing mean square error at the time dimension. However, Wiener filter with low order will lose its efficiency in high-speed communication environments, while Wiener filter with high order suffers from the problem of high computational complexity. In this paper, we analyze the relationships among Wiener filter with different orders and their corresponding application scenarios. Furthermore, based on the analysis, a pilot symbol design criterion for high-speed communication environments and a simplified Wiener filter based channel estimation technique are proposed, respectively.
