技術說明

本發明係揭露一種可應用於多輸入多輸出通道解碼系統之候選人清單擴增裝置及其擴增方法。本發明所提出之路徑擴增方法可擴增候選人清單中之路徑以便於系統用於計算可靠度資訊，另一方面，本發明另提供一額外之校正項來動態補償可靠度資訊之準確度，進而大幅提昇多輸入多輸出系統之偵錯能力以及整體效能。 The present invention discloses a candidate list augmentation apparatus with dynamic compensation in the coded MIMO systems. The proposed path augmentation technique in the present invention can expand the candidate paths derived from the detector to a distinct and larger list before computing the soft value of each bit. Consequently, the detector is allowed to deliver a smaller list, leading to reduction in computation complexity. Moreover, an additive correction term is introduced to dynamically compensate the approximation inaccuracy in the soft value generation, which improves the efficiency and performance of the coded MIMO systems.
