Abstract

A new sidelobe cancelling scheme and its adaptive algorithm are proposed. The proposed scheme employs an adaptive compensator at the output of the conventional generalized sidelobe canceller in order to reduce undesirable fluctuations in the adaptive filter coefficients after convergence. A linear prediction error filter is utilized as the adaptive compensator. According to computer simulations, the proposed scheme yields better performance than the conventional one.
