This paper analyzes the average capacity for a wireless network with joint opportunistic scheduling and wireless network coding. The capacity and the optimal power allocation scheme are derived for a multiuser fading broadcasting channel with perfect channel side information at the transmitter. The packets generated by the source nodes are encoded prior to the transmission to the relay node. The received encoded packets are mixed by XOR operation at the relay node and then broadcasted to the destination nodes. The encoder in the source nodes is designed in such a way that each destination node can give different interpretation of the received packets with their own side information. From the numerical and simulation results, we can see that the proposed simultaneous power and rate adaption for wireless network coding with opportunistic scheduling can significantly improve the average channel capacity.
