We report results of large vocabulary continuous speech recognition (LVCSR) experiments, conducted using speech data read over cellular and landline phones. Specifically, we compare (using stereo recordings) the speaker-independent and speakeradapted recognition word error rates (WERs) measured over cellular and landline networks, with those measured using a closetalking noise-canceling headset...

Wide dynamic range compression has become the mostly used signal processing strategy for mild to moderate hearing losses although there is still some discussion going on regarding the details of such compression systems. Furthermore, sophisticated signal processing strategies such as automatic program selection, adaptive digital directional microphones and sophisticated noise canceling schemes ...

In this paper, we design coordinated beamforming at base stations (BSs) to facilitate interference cancelation at users in interference networks, where each BS is equipped with multiple antennas and each user is with a single antenna. By assuming that each user can select the best decoding strategy to mitigate the interference, either canceling the interference after decoding when it is strong ...

Abstract—A convenient method for canceling the parasitic winding capacitance of integrated electromagnetic interference (EMI) filter is proposed. Based on the concept of split ground structure, mutual inductances and structural capacitances can be appropriately utilized to expand the effective frequency range in common mode (CM) noise suppression. Compared with the former approaches, it require...

The non-linear effects that have been observed in adaptive filtering scenarios arc explained from the point of view of the structure that underlies the desired data. While the model structure used by the conventional adaptive filter is a linear combination of lapped-dclay line signals, that adaptive filter model does not generally correspond to the structure that best describes the desired data...

Ultra-wideband (UWB) impulse radar plays an important role in contactless vital sign (VS) detection. The VS can be extracted remotely by acquiring the oscillations in the human chest. Unfortunately, it is usually challenging to identify VS due to the low signal-to-noise ratio (SNR) only based on the traditional fast Fourier transform (FFT) especially in complicated conditions. To extract VS acc...

Recent efforts to improve imaging quality of extremely large telescopes are based on compensating for structural vibrations with a compensation mirror canceling out the optical pathway deviations caused by vibrations of the telescope structure. To drive this mirror, the displacement of optical elements has to be reconstructed online from accelerometer measurements. The goal is to obtain high re...

Selectively canceling signals at specific locations within an acoustical environment with multiple listeners is of significant importance for home theater, teleconferencing, office, industrial and other applications. The traditional noise cancellation approach is impractical for such applications because it requires sensors that must be placed on the listeners. In this paper we propose an alter...

We study the evolution of a Bose-Einstein Condensate (BEC) in two-state superposition due to inter-state interactions. Using population imbalanced dynamic decoupling scheme, we measure interactions while canceling intra-state density shifts and external noise sources. Our measurements show low statistical uncertainties for both magnetic sensitive insensitive superpositions, indicating that succ...

In this thesis, we consider the interference cancellation problem for the broadband digital aeronautical communication system. We investigate the L-band digital aeronautical communication system (L-DACS) in the presence of distance measuring equipment (DME) interference. First, we describe the OFDM receiver of the LDACS1. In addition, we discuss the impacts of the DME spectrum on the subcarrier...
