JEL C10 * G20 ********** This research, which aims at forecasting intra-daily volatility of returns, shows that realized volatility seems to be the best methodology to predict high frequency volatility compared to more sophisticated models like the UHF-GARCH processes. When analyzing...

The development and antenna range demonstration of an eight-element, optically powered, directly modulated UHF fiber-optic (FO) manifold is described. Low power consumption, active and passive-active laser diode (LD) drives are used to reduce the link noise figure (NF) to below 3 dB with...
