A Novel FH Signal Detection Model

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.
