摘要

由于有主用户信号的存在和部分射频器件具有不可消除的非线性特性

将在射频接收机前端中产生三阶交调等干扰信号。为了减小干扰信号的影响

从射频接收机前端的角度分析了主用户信号对动态频谱共享无线通信系统的干扰特性

得出了频谱共享无线通信系统工作信道的选择约束条件

遵循此约束条件可以降低干扰信号带来的负面影响

保障频谱共享无线通信系统的通信质量。最后

在UHF频段动态频谱共享无线通信系统中

实验验证了工作信道选择约束条件的有效性。

Abstract

Because of the existence of primary user signals and the inevitable nonlinearity of some RF devices

the inter-ference signals such as three-order intermodulation signal would be produced in the front-end of RF receiver.To reduce the impact of interference signals

the interference which was caused by primary user signals to dynamic spectrum shar-ing wireless communication system was analyzed on the front-end of RF receiver side.Then

the restriction on opera-tional channel selection of dynamic spectrum sharing wireless communication system was derived.By following the re-striction

the negative effects caused by interference signals could be reduced and the quality of communication in dy-namic spectrum sharing system was guaranteed.Finally

availability of the restriction on operational channel selection is verified experimentally in UHF dynamic spectrum sharing wireless communication system.
