Adaptive noise cancellation using multichannel lattice structure.
This thesis presents a multichannel adaptive noise cancellation technique (MCLS) for cancelling the noise over nonlinear transmission channel. The technique applies to the situation in which the reference signal and noisy primary signal are collected simultaneously. The coefficients of the …

Magnetocardiography in unshielded environment based on optical magnetometry and adaptive noise cancellation
… of optically-pumped quantum magnetometers and an adaptive noise cancellation for heart magnetic field measurement within a magnetically-unshielded environment. Optically-pumped quantum magnetometers are based on the use of the atomic-spin-dependent optical properties of an atomic medium. An …

Background Noise Reduction in Wind Tunnels using Adaptive Noise Cancellation and Cepstral Echo Removal Techniques for Microphone Array Applications
Two experiments were conducted to investigate Adaptive Noise Cancelling and Cepstrum echo removal post-processing techniques on acoustic data from a linear microphone array in an anechoic chamber. A point source speaker driven with white noise was used as the primary signal. The first experiment …

Evaluation of several techniques for enhancing speech degraded by additive noise in mobile radio environments
… for enhancing speech degraded by additive noise in mobile cellular communications. The primary goal of this multi-stage study was to examine adaptive noise cancellation techniques in which one microphone is used to measure the speech plus noise signal and another microphone is used to form …

Motion-aircraft resistant design of photoplethysmograph ring sensor for driver monitoring
… flanks have been eliminated using a customized Adaptive Noise Cancellation algorithm. Both the lab results and the road test results have suggested that the new Ring Sensor is indeed capable of rejecting motion artifacts in all three possible motion axes and producing considerable amount of …

On Ways to Improve Adaptive Filter Performance
Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. The performance of an adaptive filtering algorithm is evaluated based on its convergence rate, misadjustment, …
