A method and a device (60) for estimating channel coefficients in a multi carrier system operating in accordance with a block-code based transmit diversity scheme, in which a data content of a code matrix is multiplexed in a frequency domain are described. The method comprises determining a phase ramp (ϕest) in the frequency domain or an equivalent ( DELTA t) thereof in the time domain, the phase ramp (ϕest) or the equivalent ( DELTA t) thereof being comprised within a receive signal (Y) after timing synchronizatio n, processing the receive signal (Y DELTA t) to remove the phase ramp (ϕest) or the equivalent ( DELTA t) thereof and estimating the channel coefficients on the basis of the processed receive signal. <IMAGE> |
