Research On Application Of Network Coding And Cooperative Communication In LTE Uplink Key Technology

In order to satisfy the demand of multi-rate and multi-service communication, next generation of wireless telecommunication systems need to provide better mechanism and technology to both speed up data transmission and better serve all demands of QoS. As a virtual technology of MIMO combining advantages from both diversity technique and relay transmission, cooperative communication combines has attracted exclusive attentions in industries. Network coding theory is an important break-though in network communication and development. The gateway nodes in network not only focus on simple store-and-forward, but also encode the information that passes by; therefore, the coding has enlarged the capacity and stability of entire network.This article focuses on the study of LTE uplink multi-user MIMO. Firstly, the basic concepts, system architecture and major requirements as well as the targets of the LTE are introduced. Then, cooperative communication technologies and network coding techniques are described separately. Relay coordination is compared with the cooperative. At last, the dissertation seeks to apply the plan of network coding in cooperative communication system, mainly focusing on research and analysis in system performance and implementation alternatives, etc. So this method provides the LTE uplink multi-user MIMO an effective way to achieve.
