Abstract :
In this paper a design for implementation of an ANC system with online secondary path modeling on FPGA devices is proposed. There are two adaptive units in this ANC system, the adaptive main control filter with the FxLMS algorithm and the adaptive modeling filter with the LMS algorithm for updating the adaptive coefficients array. Computer simulations show that the proposed design achieves the same performance as the existing methods.
