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.

@@@@With the application of CR and antenna array techniques, a MAC protocol for cognitive Anti-jamming communication is proposed. In this protocol, the whole communication band is divided into two layers, namely the control channel layer and the traffic channel layer, and the traffic channel is supported by the control channel. Each communication terminal is equiped with a sensing antenna and a four-element antenna array. The four-element antenna array works in multi-antenna way or AAA way at different stages of the communication. For the multi-antenna rendezvous, the array quorum-based system algorithm by K. Bian and J. Park is studied, and thus multi-antenna rendezvous algorithm proposed. Analysis indicates that the proposed algorithm is of excellent performance.
