摘要
Method and apparatus of obtaining better detection performance by improving matrix condition for an M×N over-determined MIMO system are disclosed. The condition of a matrix to be inverted for solving various detection problems is improved by reordering equations of the original MIMO system, resulting in a reordered channel matrix and reordered received signal vector so that the top N×N sub-matrix has the largest determinant among all N×N sub-matrices of the reordered channel matrix. The disclosed method may be used to obtain a more accurate estimate of the transmit data bits.
