摘　　要：针对在非高斯环境下,基于最小均方算法估算系统权值较差的问题,研究了一种新的箕舌线三次样条插值算法抑制脉冲干扰。通过引入鲁棒性较强的箕舌线函数,与样条插值算法结合,形成箕舌线样条插值算法。仿真实验表明:文中所提算法能够精确估计系统权值,较有效地抑制了脉冲干扰。In the non-Gaussian environments,system weight estimation based on the least mean squqre algorithm is poor,so a new versoria cubic spline interpolation algorithm is studied to against impulsive interference.The versoria function is introduced because of strong robustness,then versoria spline interpolation algorithm is formed by combining the versoria function with spline interpolation algorithm.Simulation results show that the proposed algorithm can precisely estimate the system weight and effectively suppress impulsive interference.
