To make synthesized speech sounds more natural, one would prefer using a larger size of speech data base. However, when we adopt manual segmentation method in making a large size data base, the procedure would be very time-consuming and the constructed data base would be in consistent. Consequently, automatic segmentation using speech recognition system has been used for making a large size of speech...
In this paper, we present a new timing recovery method using Gardner TED (Timing Error Detector) with a parabolic peak interpolation in underwater acoustic communication. The proposed algorithm has faster timing recovery speed and more accurate than Gardner TED because the sampling values are moved consistently to maximum or minimum point using parabolic peak interpolation. The simulation result shows...
In this paper, we study the possibility and the performance of PSSK(Phase Shift Silence Keying) and PSPM(Phase Shift Pulse-position Modulation) technique for low power communication. Every Mary PSK(Phase Shift Keying) symbol of PSSK that was proposed for low power communication in WBAN(Wireless Body Area Network) has the silence period for a half period of symbol. Similarly, PSPM is a kind of PSK...
In this paper, a decision feedback equalizer(DFE) is applied to the PSSK(Phase Shift Silence Keying) and PSPM (Phase Shift Pulse-position Modulation) for low-power communication in underwater sensor network. All of the M-ary PSK(Phase Shift Keying) symbol of PSSK that was proposed for low power communication in WBAN(Wireless Body Area Network) has the silence duration for a half period of symbol....
Long-term ovariectomy-induced metabolic changes such as insulin resistance and glucose intolerance might be caused directly by estrogen deficiency and may occur partly as secondary effects of obesity arising due to the orexigenic effects of estrogen deficiency. Long-term estrogen treatment prevented those by exerting anorexigenic and metabolic actions in ovariectomized mice. However, the effect of...
