摘要
A method in a receiver node (110, 115) is disclosed. The method comprises converting (604) a received time-domain signal (305, 405) to a frequency-domain signal, and obtaining (608), for the frequency-domain signal, an estimate of a frequency offset between a particular transmitter of one or more transmitters of interest and a receiver of the receiver node. The method comprises obtaining (612) a frequency compensated signal by applying a first frequency offset to compensate for the estimated frequency offset, and obtaining (616) a first channel estimation from the frequency compensated signal. The method comprises obtaining (620) a second channel estimation from the first channel estimation by applying a second frequency offset to the estimated channel, wherein the second frequency offset is the opposite of the first frequency offset.
