APPARATUS AND METHOD FOR CHANNEL ESTIMATION USING COMPRESSIVE SENSING

摘要

An apparatus and method for channel estimation comprising obtaining a response matrix G(l) using Q quantity pilots; constructing a sensing matrix Wsensing based on K quantity tones, L quantity symbols and P quantity multipaths; and using compressive sensing channel estimation to determine an equivalent channel matrix Gp(i) based on the response matrix G(l) and the sensing matrix Wsensing.
