Abstract :
A block implementation of a high-speed adaptive noise canceller is proposed. First, the block recursion equation is derived by the recursion equation in the time domain. Secondly, the block implementation of the IIR adaptive noise canceller is proposed in which the convergence rate is improved by changing the filter Q-factors. Finally, the usefulness of the proposed block implementation is verified by computer simulations
