This paper elaborates on the design of Multiple Serially Concatenated Multiple Parity-Check (M-SC-MPC) codes, that are a class of structured Low-Density Parity-Check (LDPC) codes recently proposed by the authors. M-SC-MPC codes are obtained as the serial concatenation of simple component codes, and their associated Tanner graph can be free of short length cycles. In this paper, we adopt a modified...
In this paper we report design examples of multiple serially concatenated multiple parity-check (M-SC-MPC) codes, we have recently proposed, that can be suitable for application in high speed wireless networks. We consider some low-density parity-check (LDPC) codes included in the mobile WiMax standard, and compare their performance with that of M-SC-MPC codes having the same parameters. Our results...
Computation of the undetected error probability for error correcting codes over the Z-channel is an important issue, explored only in part in previous literature. In this paper we consider the case of Varshamov-Tenengol'ts codes, by presenting some analytical, numerical, and heuristic methods for unveiling this additional feature.
