Analysis On Multi-Source Cooperative Communication Network

In the future wireless communication, the cooperative communication network will be a hot topic. The cooperative communication technique has attracted much attention for providing higher data transmission rate and increasing the diversity order. However, much of the former references are based on the cooperative communication network with single source, but in practical applications, there are usually multiple sources working in the cooperative communication network simultaneously. Therefore, in this thesis we will analysis multi-source cooperative communication network.When multiple users communicate with each other in the cooperative communication network simultaneously, the inference between each other cannot be avoided. Therefore, in Section III and Section IV, we consider the outage performance of cooperative communication networks under co-channel interference. In Section III, we investigate decode-and-forward cooperative diversity system with co-channel interference under independent but not necessarily identical Rayleigh fading. Since the best relay may not be available due to some scheduling or load balancing schemes, we consider the Nth best relay selection scheme. In Section IV, we investigate the scenario that the normal communication channel is Nakagami-m distributed but the co-channel interference is k-μ distributed and η-μ distributed.The appearance of network coding makes the multi-source communication without interference possible, of which, the most important one, as well as the most easy one is two-way relaying communication. Hence, in Section V and Section VI, we investigate the performance of two-way relaying communication. In Section V, based on the former investigation, we analysis the average error bit rate of two-way relaying system under cascaded Nakagami-m channel. In Section VI, we investigate outage performance of two-way fixed gain amplify-and-forward relaying system with asymmetrical traffic requirements.
