摘要
对基于信道化处理的跳频信号检测模型进行了研究.在介绍并推导了该检测结构的基础上,分析了该模型运算复杂度过高的原因,设计了一种基于分层处理的跳频信号检测模型.该模型通过对信号进行分层处理,减少了监控无用信道的面积,较大幅度降低了模型的运算量,提高了模型对资源的利用率,提升了模型的实用价值.仿真结果表明,改进后模型的运算量得到了大幅降低,验证了模型的有效性.
The detection model of Frequency-Hopping（FH） signal based on channelization is studied.After introducing and deriving the traditional detection model,the reason why the complexity of this model is high is analysed and a kind of step-division detection model is presented.By the operation of step-division,the useless bandwidth monitored is reduced,the computation is reduced largely and the utilization efficiency of the resource for the model is increased.After deriving the computation formula of every step-division,a kind of assembly-line model is presented.It can reduce the computation further and enhance the practical value of the model.The simulation results show that the computation of the improved model is reduced largely comparing with the condition model.
