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.
