摘要
Abstract
A combined algorithm for broadband active noise control is proposed to achieve a high noise control effect. Two algorithms, namely the filtered-X LMS algorithm and the DFT-frequency sampling filter (DFT-FSF) based algorithm are combined together to form the proposed algorithm. The algorithm enables wide band and narrow band noise controls simultaneously. It can achieve the control effect up to 45 dB for sine wave noise and the average control effect up to 15 dB for band limited white noise. The performance of the algorithm is demonstrated by simulation results.关键词
