"WebApr 29, 2024 · In a sense, the term “sphere decoding” is a misnomer as no “decoding” actually takes place. Decoding implies that error encoding has been applied to the source information bits, but this is not a requirement for the sphere decoder. As such, some authors have preferred the term “sphere detection”. " - Sphere decoding matlab

WebMay 16, 2015 · Abstract. In order to reduce the complexity of hard-output K-best decoding algorithm in multiple-input multiple-output (MIMO) systems and guarantee performance of the system, we propose a bit-sort (BS) strategy based on bit counting operation in hardware implementation for the K-best decoder. The proposed BS K-best algorithm finds out the ...
