Abstract
Decentralized systems are appealing due to their reduced complexity and flexibility. A class of decentralized multi-channel active noise control (MCANC) systems has been developed in this paper. In the first part of the study, a modified filtered-x least mean square/fourth (FxLMS/F) algorithm, which offers improved noise reduction performance over the conventional FxLMS/F algorithm, was developed for MCANC. Further, to reduce the computational complexity of the proposed MCANC system, a nearest Kronecker product (NKP) decomposition strategy has been incorporated to develop decentralized versions of FxLMS/F algorithms. The proposed algorithms have been shown to offer enhanced noise reduction at reduced computational complexity when applied for noise control for narrowband noise, bandlimited white noise, traffic noise and wind noise.
期刊介绍：
The IEEE/ACM Transactions on Audio, Speech, and Language Processing covers audio, speech and language processing and the sciences that support them. In audio processing: transducers, room acoustics, active sound control, human audition, analysis/synthesis/coding of music, and consumer audio. In speech processing: areas such as speech analysis, synthesis, coding, speech and speaker recognition, speech production and perception, and speech enhancement. In language processing: speech and text analysis, understanding, generation, dialog management, translation, summarization, question answering and document indexing and retrieval, as well as general language modeling.
