基于S方法熵测度优化的跳频信号参数估计
Parameter Estimation of Frequency-Hopping Signals Based on Entropy Measure Optimization of S Method
摘要
Abstract
A method for estimating the parameters of frequency-hopping ( FH) signals was described based on entropy measure optimization of S method ( SM). This method designs parameter estimation algorithm after obtaining optimal time frequency distribution, which the parameter of FH signals such as hop During, hop timing and hop frequencies can be estimated without any a priori knowledge. In addition,the analytical results were simulated under Gaussian noise conditions. The results shown that the deviation and variance of estimation and the complexity of the optimization process has been lowered by the proposed method.关键词
