While terahertz (THz) communication systems, operating from 100 GHz to 1 THz, have the potential to exploit wide swaths of unused spectrum for ultra-high bitrate communication, there are significant challenges. Particularly, the strong absorption of water vapor can result in very high atmospheric attenuation. We modeled a ground to geostationary satellite link and found that using large aperture THz...
High error rate in speech recognition is largely due to effects of phone local mismatch caused by unclear speaking or noises. In this paper, we propose an approach of using local mismatch phone to improve the reliability of confidence measure. The features of local mismatch phone can be extracted from the recognition phone sequence by computing occurrence frequency of each phone and comparing with...
