  • Patent number: 11777585
    Abstract: A wireless receiving apparatus generates an N?×B? weight matrix W whose columns are orthogonal to each other by decomposing an estimated N?×M? channel matrix into the N?×B? weight matrix W and a B?×M? matrix containing two or more non-zero matrix elements in each column, where B? is an integer less than or equal to N?-1 and greater than or equal to M?. Alternatively, the wireless receiving apparatus generates a combination of an N?×B? sub-weight matrix W1 and at least one second sub-weight matrix, where the product of the sub-weight matrix W1 with the at least one second sub-weight matrix is equal to the weight matrix W. The wireless receiving apparatus performs receive beamforming on received signals of N? receiving antennas using the weight matrix W or the sub-weight matrix W1. The wireless receiving apparatus then performs a BP algorithm using receive-beamformed signals.
