Turbo编码LTE上行中继技术研究

Research on Turbo Coding LTE Uplink Relay Technology

本文指出协作通信通过引入中继信道,在用户和基站之间产生了独立路径。为了提升中继系统的性能,本文选用Turbo编码分别处理源节点和中继节点的信息,目的节点仅需要对解调后的用户信息和中继信息进行Turbo译码处理即可,进而对LTE上行系统在衰落信道与多用户工作条件下的性能进行有效提升。

This paper points out that collaborative communication creates independent paths between users and base stations by introducing relay channels.In order to improve the performance of the relay system,this paper uses Turbo coding to process the information of the source node and the relay node separately.The destination node only needs to perform Turbo decoding on the demodulated user information and relay information,thereby effectively improving the performance of the LTE uplink system under fading channels and multi-user working conditions.
