ABSTRACT:
A method of receiving information includes receiving a vector of signal values for a transmitted codeword in antennas of a MIMO receiver array in each of a sequence of time slots. Each vector forms one row of a matrix Y. Each antenna receives the signal values of one column of the matrix Y over the sequence of time slots such that one of the antennas receives the signal values of each column of the matrix Y. The method also includes evaluating a vector S(0, . . . , 0) for an associated zero m-component vector (0, . . . , 0). The vector S(0, . . . , 0) is given by a Hadamard transform of the diagonal part of the square matrix Y·Y†.
