Candidate bit based bit-flipping decoding algorithm for LDPC codes

摘要

A novel hard-decision decoding algorithm for low-density parity-check (LDPC) codes is proposed in this paper. This algorithm employs the correlation information among the column vectors of the parity-check matrix and syndrome vector for decoding. It does not require soft information, and has low decoding complexity. Simulation results show that the proposed decoding algorithm could provide an effective tradeoff between error performance and decoding complexity.
