This work shows a PNLMS-based algorithm that incorporates other techniques for PNLMS to be less complex. MMax, SAG and Power-of-Two Quantization are considered in this hybrid of algorithms.

回声消除系统使用自适应滤波器模拟回声信道，自适应滤波器的阶数对回声消除效果具有重要的影响，合适的阶数可以提高回声消除效果。通过回声消除仿真对比实验显示，本算法的滤波器失准系数低于 NLMS、PNLMS 算法。-The echo cancellation system uses an adaptive filter to simulate the echo channel. The order of the adaptive filter has an important effect on th
