Abstract
A novel wireless distributed fountain coding scheme is proposed for wireless distributed networks. In this scheme, a multiplicative network coding method is adopted instead of exclusive-or (XOR) network coding. Thus, the processing complexity of the relay can be reduced, and the error propagation can be avoided. Moreover, the degree distributions of the proposed coding scheme are derived and the performance is analyzed asymptotically using semi-Gaussian approximation analysis technique. Furthermore, an efficient optimization method employing linear program is presented to optimize the degree distributions of the proposed scheme. Simulation results reveal that with optimized degree distributions, the proposed scheme has good performance on additive white Gaussian noise (AWGN) channels and outperforms the scheme using alternate forwarding.
