Description
Summary:This paper attempts to study the implementation scheme of channel estimation based on the ECMA368 standard. In this paper, we discussed the interpolation problem of null subcarriers. The interpolation DFT channel estimation algorithm is recommended for the ECMA368 standard. Compared with the traditional LS channel estimation, the performance is greatly improved when the channel length is smaller than the guard interval. Then an iterative filtering based channel estimation algorithm is proposed to reduce the influence of colored noise.
