LB communication systems can be considered as a potential candidate for ultra LPWAN because of their low cost and power consumption. In this paper, we comprehensively analyze modulation from various aspects, i.e., temporal, spectral, error performance characteristics. First, propose signal model signals that accounts the limited number loads in tag. Then, investigate spectral properties signals...

Though spectral subtraction has widely been used for speech enhancement, the spectral order β set in spectral subtraction is generally fixed to some constants, resulting in the performance limitation to a certain degree. In this paper, we first analyze the performance of the β-order generalized spectral subtraction in terms of the gain function to highlight its dependence on the value of spectr...

• The extent to which bifacial spectral effects are dependent on the albedo, sky conditions, and mounting structure quantified. Backside mismatch can be reasonably approximated using albedo measurements with just 5–8 narrow band channels. normalized difference vegetation index is a good predictor of backside present in systems. An open access dataset consisting global horizontal irradiance, bea...

Spectral analysis considers the problem of determining (the art of recovering) the spectral content (i.e., the distribution of power over frequency) of a stationary time series from a finite set of measurements, by means of either nonparametric or parametric techniques. This paper introduces the spectral analysis problem, motivates the definition of power spectral density functions, and reviews...

Besides conveying linguistic information, spoken language can also transmit important cues regarding the emotion of a talker. These prosodic cues are most strongly coded by changes in amplitude, pitch, speech rate, voice quality and articulation. The present study investigated the ability of cochlear implant (CI) users to recognize vocal emotions, as well as the relative contributions of spectr...
