摘要
本文将变步长的自正交LMS算法应用到窄带干扰抑制中,并且比较了当接收信号中含有不同数量的窄带干扰时,该算法抑制窄带干扰的性能。从仿真结果可以看出,当窄带干扰的个数增多时,变步长自正交LMS滤波器的性能要优于自正交LMS滤波器。
We can suppress the narrow-band interference (NBI) with variable step size LMS algorithm. From simulation results, we can see that when the number of the NBI increases, the performance of suppressing the NBI using the variable step size LMS algorithm is prior than that of using self-orthoganalizing algorithm.
