A High Performance Feedback Active Noise Control System

In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...

On the performance of a local active noise control system

This paper presents a multichannel active system for the local control of sound around the headrest on the back of a seat placed inside an enclosure. The size of the zones of quiet produced makes the system practical only at relatively low frequencies [1]. Finally, some results of cancellation for narrowband and broadband noise are presented. Two different system configurations algorithms have ...

Optimal-sampling Active Interference Cancellation under the Minimax Criterion

In industry and academia, researchers have given more and more attention to Cognitive Radio (CR). The key idea of CR is to make it possible for a wireless system to find the vacant spectrum and transfer data without interfering with licensed users (LUs). Then, OFDM is proposed as a candidate signaling technology for such applications. However, the sidelobe interference of subcarriers has become...

Individual Error Signal Design in Narrowband Active Noise Control Systems

A narrowband active noise control (NANC) system is often applied to reduce undesired noise with multiple tones whose frequencies are close. Generally, an NANC system uses a single error signal to update a bank of adaptive filters configured in direct/parallel or parallel form. This work proposes a delayless filterbank to participate the frequency components of the error signal into individual e...
