摘要
根据对频谱利用率的要求和目前实际器件水平,提出了基于认知无线电的最佳接收机结构,即中等频谱利用率接收机。使用ADS软件对射频前端的主要技术参数进行仿真,得到接收机链路及主要性能指标的仿真结果,仿真结果说明该设计基本满足现有接收机的技术指标要求。
A receiver structure based on cognitive radio is proposed which worked in intermediate fre- quency, combining with requirements of frequency spectrum utilization and device level at present. And through the ADS simulations on RF front-end with specified performance parameters, results of simulation on receiver＇s chain path and main parameters are got. The results show the system structure design proposed satisfies the technical index requirement of existing receivers.
