基于射频前端的动态频谱共享无线通信系统工作信道选择分析
Analysis of operational channel selection of dynamic spectrum sharing wireless communication system based on RF front-end
摘要
Abstract
Because of the existence of primary user signals and the inevitable nonlinearity of some RF devices, the interference 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 sharing wireless communication system was analyzed on the front-end of RF receiver side. Then, the restriction on operational channel selection of dynamic spectrum sharing wireless communication system was derived. By following the restriction, the negative effects caused by interference signals could be reduced and the quality of communication in dynamic 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.关键词
