SINGLE-AND TWO-CHANNEL NOISE REDUCTION FOR ROBUST SPEECH RECOGNITION IN CAR
automatic speech recognition robustness car noise two-channel noise reduction
2015/9/29
Hands-free operation of a mobile phone in car raises major challenges for acoustic enhancement algorithms and speech recognition engines. This is due to a degradation of the speech signal caused by re...
Comparison of Wavelet and FFT Based Single Channel Speech Signal Noise Reduction Techniques
DWT DWPT wavelet wavelet packet FFT noise control speech enhancement noise cancellation filter
2015/9/29
This paper compares wavelet and short time Fourier transform based techniques for single channel speechsignal noise reduction. Despite success of wavelet denoising of images, it has not yet been widel...
Compressed Sensing for Feedback Reduction in MIMO Broadcast Channels
Compressed Feedback Reduction MIMO Broadcast Channels
2011/2/28
We propose a generalized feedback model and compressive sensing based opportunistic feedback
schemes for feedback resource reduction in MIMO Broadcast Channels under the assumption that both uplink a...
Liftings of Reduction Maps for Quaternion Algebras
Liftings of Reduction Maps Quaternion Algebras
2011/1/18
We construct liftings of reduction maps from CM points to supersingular points for general quaternion algebras and use these liftings to establish a precise correspondence between CM points on indefin...
Finite dimensional reduction and convergence to equilibrium for incompressible Smectic-A liquid crystal flows
Finite dimensional reduction incompressible Smectic-A liquid crystal flows
2010/11/8
We consider a hydrodynamic system that models the Smectic-A liquid crystal flow. The model consists of the Navier-Stokes equation for the fluid velocity coupled with a fourth-order equation for the la...
On reduction of Banerjee Shandil semi circle
μσ-plane Banerjee-Shandil semi circle theorem
2010/9/15
In this paper, we stablish a more accurate discription of the region of confinement for the point (μ, σ) in the μσ- plane by applying the Banerjee Shandil semi circle theorem on the square of the rand...
Furthermore, we show that error output of single input single output system can be estimated over a certain class of input functions.
