Multi-Channel Active Noise Control System With Channel Equalization

View page
US Patent:
20110235693, Sep 29, 2011
Filed:
Mar 25, 2011
Appl. No.:
13/071712
Inventors:
Takeshi Abe - Garden City MI, US
Ming-te Cheng - Ann Arbor MI, US
Frederick Wayne Vanhaaften - Northville MI, US
Teik Lim - Mason OH, US
Mingfeng Li - Cincinnati OH, US
Jie Duan - Cincinnati OH, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
H04B 15/00
US Classification:
375224
Abstract:
A multiple error filtered-x least mean square (MEFxLMS) algorithm using a channel equalization virtual secondary path for an active noise control/cancellation (ANC) system for treating noise in a Multiple-Input Multiple-Output (MIMO) system. The channel equalization technique equalizes amplitude levels of the estimated response of all primary channels to overcome limitations caused by the frequency dependent property of standard filtered-x least mean square (FxLMS) algorithm, reduce the variation of convergence speed existed in the multiple channels, and improve the overall performance of the control system. The convergence property of the algorithm is analyzed in the frequency domain.

US Patent:
20160163304, Jun 9, 2016
Filed:
Dec 8, 2014
Appl. No.:
14/563109
Inventors:
- Dearborn MI, US
- Cincinnati OH, US
Ming-te Cheng - Ann Arbor MI, US
Frederick Wayne Vanhaaften - Northville MI, US
Liqun Na - Northville MI, US
Teik Lim - Mason OH, US
Mingfeng Li - Cincinnati OH, US
Guohua Sun - Cincinnati OH, US
Tao Feng - Cincinnati OH, US
International Classification:
G10K 11/175
Abstract:
An active noise control (ANC) system includes a speaker and one or more processors. The one or more processors implement an adaptive subband filtered reference control algorithm that applies thresholds to reference and error feedback signal paths such that, in response to a series of broadband non-Gaussian impulsive reference signals indicative of road noise in the vehicle having an audible frequency range of 20 Hz to 20 kHz, weight coefficients defining an adaptive filter of the control algorithm converge and permit the ANC system to partially cancel the road noise via output of the speaker.

Variable Bandwidth Delayless Subband Algorithm For Broadband Active Noise Control System

View page
US Patent:
20160163305, Jun 9, 2016
Filed:
Dec 8, 2014
Appl. No.:
14/563199
Inventors:
- Dearborn MI, US
- Cincinnati OH, US
Ming-te Cheng - Ann Arbor MI, US
Frederick Wayne Vanhaaften - Northville MI, US
Liqun Na - Northville MI, US
Teik Lim - Mason OH, US
Mingfeng Li - Cincinnati OH, US
Guohua Sun - Cincinnati OH, US
Tao Feng - Cincinnati OH, US
International Classification:
G10K 11/175
Abstract:
An active noise control (ANC) system includes a speaker and one or more processors programmed to implement a delayless subband filtered-x least mean square control algorithm. The algorithm includes a variable bandwidth discrete Fourier transform filter bank having a number of subbands such that the system, in response to a broadband white noise reference signal indicative of road noise in the vehicle, exhibits a uniform gain spectrum across a frequency range defined by the subbands and partially cancels the road noise via output of the speaker.
