Abstract

Abstract:

In order to select the relay node and improve the system throughput, a new multi-user cooperative communication protocol is proposed based on the opportunistic communication and network coding. On the basis of outage probability, each user decides whether to help forward its partner's information as a relay or not. The relay node processes its own information and the partner's information by the use of network coding, and transmits it to the receiver. The receiver can obtain several transmitters' information using coherent detection. Compared with traditional cooperative protocols, the proposed protocol can improve the average per user throughput and the network throughput in the quasi-static Rayleigh fading channel. The probability of system outage is reduced with fewer time resources.

Key words: cooperative communication, network coding, outage probability, throughput
