A New Time Delay Estimation Method Based on Lagrange Interpolation Filter in Impulsive Noise Environment
脉冲噪声环境下基于拉格朗日插值分数延迟滤波器的时延估计方法

Based on the fractional lower order theory a novel fractional time delay estimation algorithm referred to as EFMML(Explicit Fractional lower order Mix Modulated Lagrange)under a stable distributed noise environment is proposed.The convergence condition of the proposed method is analyzed in theory.Computer simulation shows that the proposed method is robust for both Gaussian and non-Gaussian impulsive noises environments.And it is more effective than FSETDE(Fractional lower order Simplified Explicit Time Delay Estimation),an existing time delay estimation algorithm under a stable distributed noise environment.
