In this correspondence, we propose a simplified QR-decomposition-M algorithm for coded multiple-input multiple-output systems based on the idea of selective branch extension. The proposed algorithm results in significant complexity reductions without observable performance losses, especially for large modulation orders where complexity reduction is most important.
