摘要
The detection algorithms based on QR decomposition can obtain good detection performance with significant complexity reduction, such as the layered orthogonal lattice detector (LORD). However, it can achieve near-optimal performance in multiple input multiple-output (MEMO) systems with two transmit antennas. In order to make it applicable to high-order MIMO systems, this paper designs a subspace detection algorithm based on WL decomposition (WLD) which alleviate the limitations of the LORD algorithm. Simulation results show that the designed algorithm can outperform the QR decomposition based M-algorithm (QRD-M) while maintaining low complexity.
