A FPGA-based Method for Modeling and Generation of the Time-varying Electromagnetic Environment
The frequency hopping radio has been widely used for its anti-interference ability.However,in the installation,testing and evaluation of short-wave frequency hopping radio,a realistic time-varying electromagnetic environment support is lacking.Hence,it is important to construct the time-varying electromagnetic environment which the short-wave frequency-hopping radio may face.To solve this problem,this paper firstly finds out five kinds of signals commonly faced by the short-wave frequency-hopping radio and extracts their time-varying parameters by signal simulations with MATLAB.After that,a model based on the traversal is proposed,which accurately reconstructs the time-varying electromagnetic environment.Finally,this model is implemented on the FPGA,which could generate a feasible time-varying signal to represent the electromagnetic environment.This device may be useful for the installation,debugging,testing,evaluation and other tasks of short-wave frequency hopping radio.
