摘要：
The number of crossband filters controls convergence rate and steady-state MSE of LMS algorithm in subband in the short-time Fourier domain, which necessitates a compromise between them due to its fixed value. Therefore, a decision to adaptively control the number of crossband filters is proposed to provide both fast convergence rate and small steady-state MSE. The advantage of the proposed algorithm is verified by the simulation.
