A novel photonic approach to the implementation of RF photonic phase shifter is proposed. It is based on a polarization dependent optical phase modulator and a dual-parallel Mach-Zehnder modulator. The phase shift of RF signal has a predefined linear relationship with the dc bias voltage of the optical phase modulator. This enables users to easily determine the control voltage needed to realize the...
A modified double sideband modulation(DSB) scheme to realize frequency doubling and wavelength reuse in the uplink is proposed. In the modified DSB scheme, by adjusting the phase difference between two arms of the intensity modulator, the optical carrier and the two first-order sidebands are generated, after beaten by the photodiode, a high spectrum purity and low phase noise millimeter-wave (mm-wave)...
Determining the total capital requirement and allocating capital to business lines are two key parts of financial and risk management for a multi-business insurance company. Several well-known methods have been proposed to calculate these qualities. Our paper considers the total capital requirement for a multi-business insurance company based on Co-TailVaR from each line level to the entire company...
