專利摘要(中)
本發明提供一種極化碼解碼裝置及其操作方法。極化碼解碼裝置包括路徑分裂電路以及節點處理電路。路徑分裂電路依照目前節點將多個先前解碼結果所對應的多個先前路徑的每一個分裂為多條候選路徑。路徑分裂電路依照在目前節點中的不可靠消息位元數量來動態決定這些先前路徑的每一個的這些候選路徑的路徑分裂數量。節點處理電路進行路徑競爭操作，以從這些候選路徑中選擇部份路徑作為多個目前解碼結果所對應的多個目前路徑。

專利摘要(英)
The invention provides a polar code decoding apparatus and an operation method thereof. The polar code decoding apparatus includes a path expanding circuit and a node processing circuit. The path expanding circuit expands each of the previous paths corresponding to the previous decoded results into multiple candidate paths according to a current node. The path expanding circuit dynamically determines the path expanding number of the candidate paths of each of the previous paths according to the number of unreliable information bits in the current node. The node processing circuit performs a path competition operation to select partial paths from the candidate paths as the current paths corresponding to the current decoded results.
