| 摘 要： | 按照均匀收敛的总体要求，通过分析不同权值抽头的均方偏差收敛过程，得到一种均匀收敛比例归一化最小均方算法．对PNLMS算法比例系数进行改进得到另一种均匀收敛算法．仿真结果表明：所提算法保持了PNLMS类算法初始收敛速度快的特点，在整个过程中获得了均匀的速度，稳态误差与NLMS算法基本相同．

| Abstract: | A uniform convergence proportionate normalized least mean square algorithms is proposed in response to uniform convergence requirement by analyzing the convergence of mean square deviations of variant weights. Another uniform convergence algorithm can also be obtained by improving the proportionate coefficients of PNLMS algorithm. Simulation demonstrates that these proposed algorithms not only maintain the characteristic of rapid initial convergence speed, but also obtain a uniform speed throughout the convergence period, with the same stable error as NLMS algorithms. |
