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.
