摘 要
本设计强调干扰环境下无线中继的性能分析。将从5G异构网络系统主要的性能指标入手,通过理论推导及仿真,分析干扰环境下中断率、误码率、信道容量等。在中继传输系统中,不论是两跳中继,还是多跳多中继系统,其信道传输的基本原理均是建立在两跳中继系统基础上的。在本设计中,将在前人研究的基础上,研究干扰环境下无线中继系统的性能,并进行分析与仿真。

Abstract
This design emphasizes the wireless relaying performance analysis in interference environment. I will analyze the main performance metrics such as outage and error probability of the communication system in interference environment, than I will make some simulation to demonstrate the result of theory analysis. In relay transmission system, either two relaying or multiple relaying, its basic principles are based on the two relaying system. In this design, the wireless relay system performance in the interference will be analysis and simulation on the basis of previous studies.
Key Words: Multiple relay; Bit error rate
