Hospital lighting is an essential embodiment of hospital modernization. With the increasingly significant role medical environment in process, both requirements various treatments and response patients to should be considered design. Avoid discomfort disgust caused by improper layout or illumination selection. To meet physiological psychological needs personnel, light buildings no longer limite...

In this study, a blind carrier frequency offset (CFO) estimation method is proposed using the time-frequency symmetry of transmitted signals weighted Fourier transform (WFrFT) communication system. Blind CFO achieved by focusing on property that results in matching signal waveforms before and after when WFrFT parameter set to certain value. Numerical simulations confirm more resistant Rayleigh ...

Carrier Aggregation is one of the vital approaches to achieve several orders magnitude increase in peak data rates. While carrier aggregation benefits have been extensively studied cellular networks, its application satellite systems has not thoroughly explored yet. can offer an enhanced and more consistent quality service for users throughout coverage via combining multiple carriers, utilizing...
