Abstract

In this paper, a variable step size LMS algorithm was introduced to eliminate the coupling interference of torpedo active electromagnetic fuze system. The variable step size will increase or decrease according to the residual error, which can achieve a faster convergence rate, a smaller steady-state error and a better adaptability to the signal-to-interference ratio (SIR) than the fixed step size. The suppression performance of the step size function with different parameters is analyzed. Numerical results are presented by comparing the performance of the variable step size LMS algorithm with the fixed step size LMS algorithm, to demonstrate the effectiveness and robustness of the variable step size LMS algorithm.
