Abstract
A weight-constrained filtered-x LMS (CFxLMS) algorithm is proposed for broadband feedforward active noise control system. Compared with the system using the normal FxLMS algorithm, the proposed system is more robust against interference to error microphone. Computer simulation results show the effectiveness of the algorithm.
