METHOD FOR EXPLOITING DIVERSITY WITH NETWORK CODING

摘要

Disclosed here is Miss-and-Forward (MF), a new method for loss-tolerant information spreading, in which a special relay called "helper" is assigned to exploit the rich diversity. In accordance to some embodiments, a network coding based scheme is disclosed which has the ability to restore the "missed" information and in the meanwhile retains the benefit of state-of-the-art batched sparse coding. A systematical design is provided to address practical issues such as helper selection and rank distribution estimation. Both numerical and simulation results show that the MF method outperforms fountain codes and existing network coding schemes, providing an information spreading technique that is well suited for use with ultra-dense networks by taking advantage of the densely deployed relays in new network settings, such as in 5G networks.
