Multichannel Adaptive Least Squares Lattice Filters for Active Noise Control
In this paper a new algorithm for multi-channel adaptive least squares adaptive filtering, using a lattice filter is proposed. The algorithm is a multi-channel numerically stable version of the adaptive least squares lattice with a priori errors and error feedback. It is adapted to active noise control using the modified filtered-Error algorithm. It is shown throw computer simulations that the ...
متن کاملAdaptive multichannel control of time-varying broadband noise and vibrations
This paper presents results obtained from a number of applications in which a recent adaptive algorithm for broadband multichannel active noise control is used. The core of the algorithm uses the inverse of the minimum-phase part of the secondary path for improvement of the speed of convergence. A further improvement of the speed of convergence is obtained by using double control filters for el...
متن کاملMultichannel Adaptive Stochastic Filtering for Active Noise Control in Personal Computers
In this paper, the feasibility of using active noise control inside personal computers is demonstrated by applying an adaptive filter to Hewlett-Packard’s Blackbird 002 Gaming PC. Conditions relating the control signals and the sound heard by an external listener are presented as a means of evaluating the hardware design before applying the adaptive filter. A multichannel stochastic adaptive fi...
متن کاملMultichannel active noise control algorithms using inverse filters
1.0 Introduction For active noise control (ANC) systems, a common approach is to use adaptive FIR filters trained with the filtered-x LMS algorithm [1], for both feedforward systems and Internal Model Control (IMC) feedback systems, in monochannel or multichannel systems. Variations of the algorithm sometimes called the modified filtered-x LMS algorithm have been published [2], which can achiev...
متن کاملSome practical insights in multichannel active noise control equalization
In this paper, a novel adaptive algorithm for equalization of periodic signals using active control is developed. This algorithm actively cancels out a single frequency without changing the amplitude levels at close frequencies. The algorithm performance is compared with that of an adaptive equalizer previously reported [1][2]. Both algorithms are used for a real multichannel system in order to...
