Abstract
The filtered-X affine projection (AP) algorithm is applied for active control of the tonal noises generated by periodic noise sources like rotating machines. The convergence analysis of a complex filtered-X (CFX) AP algorithm using multi-reference signals is then investigated. Next, computer simulation is presented to show that the CFX AP algorithm yields faster convergence than the CFX LMS algorithm.
