Abstract： |
This invention relates to a decoding method applying low density odd-even check codes of variable sphere uniform quantization including: selecting a group of parameters for decoding, initializing the soft information of the ith code cell of the LDPC code, the outer information output to the bit node I from the check node and their iterative times, decoding the variable sphere uniform quantization to the initialized and quantized soft information and outer information, totalizing all soft information and outer information of all the bit nodes to get the decodes, carrying out the following hard decision to all decode results to get the output result: if the check sum of the output result sequence is zero, or the iterative times reach to the maximum times, then the decode is finished, otherwise the time is plus with 1 to continue the decode. |
