摘要
本發明提出一種趨近最大相似度之序列式解碼方法,能夠透過一時序門檻(level threshold)在解碼的過程中,刪除不太有希望成為最大相似度的路徑,以降低解碼的複雜度。另外,本發明利用一計量値(metric),使得接收信號不需經過硬式決定的步驟,就夠透過序列式解碼得到最大相似度的解碼。
A method for near maximum-likelihood sequential decoding is provided. The method is used to a level threshold to delete the unlikely paths to reduce the decoding complexity In the other aspect, the method performs maximum-likelihood decoding through a sequential decoding by the path metric, so that a received signal does not use a hard decision procedure.
