Channel estimation method blending correlation and least-squares based approaches

摘要

A response of a channel may be estimated by correlating a received signal and a training sequence, by forming a matrix Γ based on a desired shape for the peaks of the correlation, by extracting a vector y from the received signal, and by estimating the channel response from a least-squares solution based on the matrix Γ, the vector y, and a matrix formed from the elements of the known training sequence.
