Method for determining layer stoppage in LDPC decoding

摘要

A method for determining a layer stoppage in LDPC decoding is provided. The method may include determining the occurrence of the layer stoppage to detect and record a convergence of a layer arithmetic unit after the performance of a layer decoding operation using LDPC decoding, and in a subsequent iteration operation stopping an operation of the layer arithmetic unit that has converged and repeating determining the layer stoppage for the layer arithmetic unit that has not yet converged. An output of the non-convergent layer may be diverted to the next non-convergent layer while bypassing the convergent layer without interrupting the subsequent iteration operation while maintaining the overall error correction capability.
