This brief presents a novel two-dimensional parallel sorting algorithm for high-throughput K-best detectors utilised in multiple-input multiple-output (MIMO) systems. The proposed sorting algorithm enhances the throughput by sorting a data set in parallel and avoids the relatively long latency of the traditional algorithms. This is especially important in MIMO systems utilising high-order modulation...
