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.
