Wireless Adaptive Network Coding Strategy in Multiple-Access Relay Channels

This paper considers a Multiple-Access Relay Channel (MARC) with two sources, one relay and one destination, where the relay decides what it transmits to the destination according to the outage condition of source-relay links. The outage probability and the approximate Bit Error Rate (BER) are derived, which are shown to be in tight match with Monte-Carlo simulation results. Simulation results reveal that adaptive DF strategy yields better performance than the traditional fixed DF strategies. The Multiple-Access Relay Channels (MARC) system is an important communication scenario and has been recognized as one of the fundamental building blocks for modern wireless networks.
