This letter proposes a new class of serially concatenated codes that can be viewed as Low-Density Parity- Check (LDPC) codes. They are derived from Multiple Serially Concatenated Single Parity-Check (M-SC-SPC) codes, but they use different components, that we call Multiple Parity-Check (MPC) codes. In comparison with M-SC-SPC codes, the new scheme achieves better performance with similar complexity. The proposed codes can represent an alternative to the well-known family of Repeat Accumulate (RA) codes, being based on the same principles.

Abstract
This letter proposes a new class of serially concatenated codes that can be viewed as Low-Density Parity- Check (LDPC) codes. They are derived from Multiple Serially Concatenated Single Parity-Check (M-SC-SPC) codes, but they use different components, that we call Multiple Parity-Check (MPC) codes. In comparison with M-SC-SPC codes, the new scheme achieves better performance with similar complexity. The proposed codes can represent an alternative to the well-known family of Repeat Accumulate (RA) codes, being based on the same principles.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
