摘要： Embodiments of the present invention relate to a method for implementing Turbo equalization compensation, an equalizer, and a system. The method for implementing Turbo equalization compensation includes: dividing a first data block into n data segments, where D bits in two adjacent data segments in the n data segments overlap, performing recursive processing on each data segment in the n data segments, and merging the n data segments on which the recursive processing has been performed, to obtain a second data block; and performing iterative decoding on the second data block, to output a third data block, where data lengths of the first data block, the second data block, and the third data block are all 1/T of a code length of a LDPC convolutional code. The embodiments of the present invention are applied to a receive end of a high-speed optical fiber transmission system. By performing, in an OP-BCJR unit, segmentation processing and forward and backward recursive operations on a received data block, and performing, in an LDPC convolutional code decoding unit, Turbo iterative processing on data obtained from the OP-BCJR unit, a system throughput can be effectively improved.

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.
摘要翻译：本发明的实施例提供了一种解码方法和解码器。所述解码方法包括：在对多个码字进行至少一次软判决解码之后，判断软判决解码的解码结果是否满足切换至硬判决解码的切换条件; 如果不满足切换条件，则在下一次解码期间继续使用软判决解码; 或者如果满足切换条件，则在下一次解码期间切换到硬判决解码，并且在随后的解码期间始终使用硬判决解码直到解码迭代退出。这样，当软判决解码的解码结果满足特定条件时，解码可以切换到需要较低功耗的硬判决解码，并且可以避免继续使用需要较高功耗的软判决解码，由此降低解码器的功耗而不影响解码性能。
