Low-complexity encoder for LDPC codes in space applications
2019
A low complexity encoding method and encoder architecture are proposed for the low-density parity-check (LDPC) codes in space applications recommended by Consultant Committee for Space Data Systems. This method uses the generator matrix partition and decomposition to obtain a much smaller dense core matrix. Thus, only one quarter of dense block matrices need to be implemented using the traditional circulant encoding structure. Therefore, the encoder can be implemented with lower computation and storage complexity.
