| 摘 要： | 该文提出一种新的适用于α稳定分布噪声环境的自适应滤波算法,这种算法通过使加权平均误差函数的p-范数最小来实现自适应滤波.在这种算法的基础上,该文还得到两种新的动量LMP自适应算法.将这些新算法应用于估计AR模型的参数,计算机仿真的结果表明,该文提出的算法的性能比已有LMP算法的性能要更为优越.

| Abstract: | This paper introduces a new adaptive filtering algorithm under the α-stable noise conditions, which is obtained by minimizing the weighted average p-norm of error function. Two new versions of momentum LMP algorithm can be derived from the proposed one. Computer simulations on the channel equalization under the α-stable noise conditions show that the proposed algorithms provide better estimation performance than those of the existing LMP algorithm. |
