摘要： Embodiments of the present invention provide a decoding method and a decoder. The decoding method includes: after performing soft-decision decoding at least once on multiple codewords, determining whether a decoding result of soft-decision decoding meets a switching condition for switching to hard-decision decoding; and if the switching condition is not met, continuing to use soft-decision decoding during next decoding; or if the switching condition is met, switching to hard-decision decoding during next decoding, and always using hard-decision decoding during subsequent decoding until a decoding iteration is quit. In this way, when a decoding result of soft-decision decoding meets a specific condition, decoding can switch to hard-decision decoding that requires lower power consumption, and continual use of soft-decision decoding that requires higher power consumption can be avoided, thereby reducing power consumption of a decoder without impairing decoding performance.

摘要： Embodiments of the present invention provide a decoding apparatus and method. The method includes: obtaining a to-be-decoded group; detecting whether all code words in the to-be-decoded group meet that a checksum is 0; performing a sign bit decision on the to-be-decoded group when all the code words in the to-be-decoded group meet that a checksum is 0; detecting, when all the code words in the to-be-decoded group do not meet that a checksum is 0, whether the sign bit decision has been performed on each code word in the to-be-decoded group; performing, when there is at least one code word on which the sign bit decision has been performed in the to-be-decoded group, data restoration on each code word on which the sign bit decision has been performed; and constructing a new to-be-decoded group by using each code word obtained after the data restoration and each code word on which the sign bit decision has not been performed, to perform FEC decoding. When all the code words in the to-be-decoded group meet that a checksum is 0, FEC decoding is not performed, and only the sign bit decision is performed. That is, in a process of performing multiple times of decoding on each code word, FEC decoding is not always performed every time. This reduces power consumption required by FEC decoding.
