Low Complexity Signal Detection Based on WL Decomposition for MIMO Systems
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 (MIMO) 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.
