A method is disclosed for signal detection in a wireless communication system that includes multiple-antenna arrays for transmission and reception. The method involves multiplying a vector of signals collected from respective receiving antennas by a nulling vector, such that the resulting vector product provides an estimated value corresponding to a specific one of the transmitted signals. A respective such multiplication is performed to detect each of the transmitted signals. In contrast to related methods of the prior art, each nulling vector is obtained from a channel matrix of estimated channel coefficients without performing any matrix inversion operations, and only a single pseudoinverse related to the channel matrix is computed. As a result, numerical stability is improved and the computational complexity of the method is reduced by an order of magnitude relative to methods of the prior art.
