| 摘要: |
| 为了促进自适应滤波器的滤波性能,建立了一种变步长的伪仿射投影(Pseudo Affine Projection,PAP)算法。通过使得权值误差在输入信号方向向量的误差等于0,结合正交迭代算法,获得了PAP算法的优化迭代步长。仿真结果表明:基于优化迭代步长的PAP算法促进了自适应滤波器的收敛性和失调量。 |

| Abstract: |
| Aiming to improve the performance of adaptive filtering,we present a pseudo affine projection(PAP) algorithm with variable step size. Setting the weight error to be zero in the direction vector and using the orthogonal direction algorithm,we obtain the optimal step size for the PAP algorithm. The simulation results and their analysis show preliminarily that the PAP algorithm with the optimal step-size improves the adaptive filtering convergence and misadjustment. |
