摘要
针对当前通信技术静态频谱分配的有限频谱资源问题,借鉴认知无线电系统相关技术,以具体项目为依托,针对干扰和变距情况下数据链系统的正常通信问题,设计有限频谱的动态感知和自适应变速算法,并在数据链实物端机上进行验证与测试,达到系统预期效果,实现自动、自适应、动态可靠的通信保障。
In view of the limited spectrum resources of the static spectrum allocation in current communication technology,based on the related technology of cognitive radio system and specific projects,to resolve the problem of the normal communication of data link system in the presence of interference and variable distance.The dynamic sensing and adaptive transmission algorithm of finite spectrum which is verified and tested on the physical data link terminals is designed to achieve the system prospective effect and realize the communication guarantee of automatic,adaptive and reliable state.
