Abstract

A method and a circuit (44) for estimating channel coefficients in a multi carrier transmit diversity system operating in accordance with a block-coding scheme is described. The method comprises determining from a receive signal (Y) for each channel estimated channel coefficients (ĥ) comprising interference components from adjacent channels artificially introduced during the estimation, deriving estimates for interference components and determining interference-compensated estimates (ĤF+IC) for the channel coefficients on the basis of the estimates for the interference components.
