Abstract

A multi-stage decoding algorithm for improving the decoding performance of bits encoded with a linear error-correcting block code of small or medium block length is provided. The algorithm comprises an input stage, at least two intermediate stages and an output stage. For each of the stages (except for the last intermediate stage and the output stage), a certain number of bit positions is selected and set to a maximum possible absolute LLR value. The output data of each stage is used to compute the input data of the next stage. Each of the intermediate stages executes a specified number of parallel decoding runs, and the input data for each of the intermediate stages is generated based on the output data of the previous intermediate stage and initial LLRs obtained after demodulation. The bit positions set to the maximum possible absolute LLR value in the previous stage cannot be used again in the next stage. At the output stage, only one decoding run is executed, for which input data are formed based on the initial LLRs and the LLRs obtained at the last intermediate stage.
