摘要 By constructing an accumulated-crossover relationship in multiple parallel concatenated single parity check （M-PC-SPC） codes, a class of error-correcting codes, termed multiple accumulated-crossover parallel concatenated single parity check （M-ACPC-SPC） codes, is proposed. M-ACPC-SPC codes possess linear encoding complexity and can be decoded iteratively with low complexity by the sum-product algorithm （SPA）. Simulation results show that M-ACPC-SPC codes have lower error floors than M-PCSPC codes with the same dimension, and when the dimension is 5, M-ACPC-SPC codes achieve bit error rate （BER） better than （3, 6） regular low density parity check （LDPC） codes.
