说明: 子带自适应滤波算法是处理长阶声学回声抵消问题的重要方法之一。结合房间声学的特点, 对各子带采用不同长度的FIR 滤波器进行滤波, 将有限的资源进行更合理的分配, 节省了资源和计算量, 并在一定程度上提高
了收敛速度。
(Subband adaptive filtering algorithm is the deal with a long acoustic echo cancellation problem of order one of the important ways. Combination of room acoustics characteristics of the different sub-band FIR filter length filtering, limited resources in a more rational distribution, saving resources and computation, and to some extent improve the convergence rate.)
