Virtual network(VN) mapping deals with the allocation of network resources from the shared physical substrate to individual VNs is one of the key challenges for the application of realising network virtualisation. Whereas a variety of state-of-the-art algorithms have attempted to address this issue from different aspects, the challenge still remains for mapping VNs across multiple network domains...
The authors study the optimisation of the rate-compatible (RC)-irregular-repeat-accumulate (IRA) codes for asymmetric Slepian??Wolf coding to deal with flexible correlated sources. By assuming two different additive white Gaussian noise channels, the authors formulate a non-uniform extrinsic information transfer method to optimise the degree distribution of RC-IRA codes. The parity check matrices...
