应用认知无线电技术和阵列天线技术,提出了一个军事通信中认知抗干扰通信的MAC协议。把整个通信频段分为控制信道和业务信道两层信道,并由控制信道支撑业务信道。每个通信终端装备一部感知天线和一部4元天线阵。4元天线阵有两种工作方式:多天线独立方式和阵列天线方式。以多天线方式在控制信道完成交会,以阵列天线方式定向发射或定向接收控制信息和业务信息。通过对交会算法研究和改进,提出了多天线交会算法,并验证了此算法性能非常优越。
Using cognitive radio technology and array antenna technology, a MAC protocol for cognitive anti-jamming communication in military communications was proposed. The whole communication frequency band is divided into two channels of control channel and traffic channel, and the control channel supports the traffic channel. Each communication terminal is equipped with a sensing antenna and a 4-element antenna array. 4 yuan Antenna array has two kinds of work: multiple antenna independent way and array antenna way. The multi-antenna method is used to complete the rendezvous on the control channel, and the directional antenna is used for directional transmission or directional control information and service information reception. Through the research and improvement of rendezvous algorithm, a multi-antenna rendezvous algorithm is proposed, and the performance of the algorithm is proved to be superior.
