Abstract

Since ultra-wideband (UWB) radio fuze echo signal is covered by high-frequency noise, a variable step-size least mean square (LMS) adaptive filtering algorithm based on error feedback control was proposed. According to constant coefficient in two existing algorithms is a function of the error, the nonlinear relationship model between step and error was proposed, and also the performance of the new algorithm was analyzed by MATLAB. Simulation results show that the algorithm on the convergence rate and steady-state error have been greatly improved. The new algorithm has good performance and the processing to ultra-wideband radio fuze echo signal obtains satisfactory results, which is convenient for practical application.

Key words： UWB radio fuze; echo signal; error feedback; adaptive filter; convergence rate; steady-state error
