摘　　要：传统的电台设计以高速跳频体制来应对复杂电磁环境,但该体制灵活性差,实际的通信效果和抗干扰能力不如预期,针对此情况提出传统跳频+智能选频跳频的MIX链路传输机制解决方案。设计基于认知无线电的智能选频技术,使得网络节点设备始终工作于当前最佳的信道条件下,达到任何时间任何地点的高度可靠通信和对频谱的有效利用的目的。对其中的基于网络的电磁环境快速认知、本地频谱感知、主动波形感知、网络频率资源规划自适应选频互干扰问题解决等关键技术进行了分析和研究。The traditional radio design uses a high-speed frequency hopping system to cope with complex clectromagnetic cnvironments,but the flexibility of this system is poor,and the actual communication effect and anti-interference ability are not as expected.In response to this situation,a MIX link transmission mcchanism solution combining traditional frequcncy hopping and intelligent frcquency selection hopping is proposed.Design intelligent frequency selection technology based on cognitive radio to ensure that network node devices always operate under the current optimal channel conditions,achieving highly reliable communication at any time and place,and cffectively utilizing the spectrum.We have analyzed and studied key technologies such as network-based rapid recognition of electromagnetic environments,local spectrum sensing,active waveform scnsing,and network frequency resource planning for adaptive frequcncy selection and mutual interference resolution.
