Reconstruction of LDPC code sparse check matrix based on modified LBP decoding

In order to reconstruct the sparse check matrix of LDPC code, a sparse check matrix reconstruction algorithm for LDPC code at high BER was proposed based on modified LBP decoding. Firstly, some bits were selected randomly from the codeword matrix to construct the codeword analysis matrix, and Gaussi...
