User-centric ultra-dense networking (UUDN) had been proposed for allowing ubiquitous services for end-users on the move based on well-deployed access points. In this paper, we studied a possible scenario of well-deployed user equipment/access point device (UAD) for UUDN due to its auto-deployment and crowd-oriented nature. Considering high PAPR signal of OFDM families for 5G waveform candidates, the...
A wireless wearable device that operated by Android phones to measure and record the skin moisture of human face is proposed in this paper. The skin moisture of human face is measured as a resistance by a simplified Electrochemical Impedance Spectroscopy. The interdigital electrode is used to contact skin directly, and also conducts square wave signal to skin surface. However, skin moisture attenuated...
