A hybridmodulation method is proposed for the HVDC system using voltage sourced converter (VSC) technology, which performs satisfactorily both in steady state and in dynamic state.
At the same time, based on conventional modulation strategies-multi-carrier SPWM applied on multilevel inverter, hybridmodulation strategies are introduced corresponding to hybrid structure.
The optimum receiver performance of a hybrid pulse phase and position modulation(PAPM) over ultra-wideband(UWB) indoor fading channel model is analyzed.
