Robust adaptive interference rejection in DS/FH hybrid system

  • According to robust estimator theory, an adaptive filter based on generalized M estimation was used to reject partial band interference in DS/FH hybrid communication system, and the robust adaptive algorithm was deduced. The performance of two M estimation functions (Huber function and Tri-weight function) which are widely used in M estimation was also compared. Monte Carlo simulation results indicate that the performance of DS/FH system using robust adaptive filter is improved remarkably in nonstationary interference environment ,and the performance of Tri-weight function excels the Huber function's obviously.
