摘要

Compared with the single tree detector, the layered orthogonal lattice detector (LORD), developed by Siti et al., is a well-known soft-output multiple input multiple output detector to exploit M parallel tree traversals to deliver data with M times of detection throughput rate. The preprocessing QR-decomposition (QRD) of the M-by-M channel matrix for the single tree detector is of complexity propo...
