Abstract:
The present invention relates to a method and a device for decoding precoded signals in a wireless communication system and network node or terminal associated therewith. The wireless communication system comprises a sender and a receiver that share a codebook containing a plurality of precoding matrices. The sender precodes at least a data signal to be transmitted with one of the plurality of precoding matrices. Said method comprising receiving signals from the sender, estimating a channel between the sender and the receiver based on a part of received signals that is known a priori, evaluating relevancies of precoding matrices in said codebook to a precoded signal in the received signals based on at least the estimated channel and the codebook according to a predetermined criterion, and selecting a precoding matrix with maximum relevancy by comparing the evaluated relevancies, and applying the selected precoding matrix for decoding the received precoded signal.
