Joint network/channel decoding algorithm for wireless networks and proof simulation

摘要

In this journal, we present a joint network/channel decoding (JNCD) algorithm for a wireless network that consists of M users. Previous works studied a small 2-user network. In our work, we consider a network that consists of M mobile station (MS), one relay (R) and one base station (BS). The network/coding process is done on the relay. In order to evaluate the performances ofJNCD,wewill fix another network which does not contain a relay. Then, the adopted reference chain will contain only M senders (MS) and one receiver (BS). The obtained results will be evaluated with a network simulator:Opnet Modeler. Then, we present two grouping algorithm: the first treat the impact of the number of nodes in each group in the network, and the second present the impact of transmission channel characteristics on node grouping.
