摘要
基于梯度信息的计算来调节自适应 IIR滤波器的系数 ,需要进行复杂的矩阵运算 ,计算量大 ,容易陷入局部收敛。本文构造了稳定性检测十分方便的二阶自适应 IIR滤波器的并联结构 ,并将遗传算法应用到滤波器的系数寻优 。
Calculation based on grads communication to adjust coefficient of adaptive IIR filter is not only difficult to be detected stability but also easy to run into part convergence. The parallel connection of the two rank adaptive IIR filters is stability, with the help of genetic algorithm, it can search globally and find the optimization.
