Error correction decoding apparatus and error correction decoding method

摘要

Error correction decoding apparatusInternal code iterative decoding circuitParameter generation circuitComprising a first control circuitThe first control circuitThe threshold and maximum number of iterations generated by the parameter generator are received as parameters.If the number of iterations has not reached the maximum number of iterations,The number of non zeros sequentially output from the internal code repetitive decoding circuit.Compare the set of recursions to the setIf the comparison result satisfies a preset stop condition,The repetitive operation by the internal code repetitive decoding circuit is stopped.
