High-Throughput Soft-Output MIMO Detector Based on Path-Preserving Trellis-Search Algorithm

In this paper, we propose a novel path-preserving trellis-search (PPTS) algorithm and its high-speed VLSI architecture for soft-output multiple-input-multiple-output (MIMO) detection. We represent the search space of the MIMO signal with an unconstrained trellis, where each node in stage k of the tr...
