By slightly modifying the Sum-Product Algorithm (SPA), the joint iterative channel decoding and network encoding algorithm is applicable to any linear channel code, e.g. Low-Density Parity-Check code (LDPC code), which is characterized by its parity check matrix \$\mathcal\{H}\$. In order to provide important insights into the proposed algorithm, we model the generalized joint channel-network coding as a dynamical system. Due to its efficient decoding, the proposed scheme is well suited for a practical wireless system, e.g. cellular network. Simulation results show that the proposed scheme outperforms other recently proposed network coding schemes with slightly increased complexity. }, booktitle={2010 IEEE 71st Vehicular Technology Conference (VTC2010-Spring)} }
