摘要：

Sub-band filtering is employed in various system identification applications. It reduces the computational complexity and adaptation time. The paper focuses on sub-band filtering for acoustic echo cancellation. A Simulink model for 2, 4, 8 sub-bands was created and simulated. The echo is created by applying a vocal test to a first Schroeder reverberator. The performance of the full- and sub-band echo canceller is measured in terms of error signal and echo-return loss enhancement.
