| Abstract(in English) | On the high carrier frequery wireless communication, multipath fading is always cling problem. Fast Frequency Hopped Spread Spectrum (FFH-SS) communication can solve this problems to change carrier frequency. We have made the MHz hopping frequency synthesizer which generate carrier frequency in FH-SS communication. This synthesizer is applicable to ourdoor multipath environment. But, FFH-SS communication requires scores of MHz hopping rate in indoor multipath environment, e. g. factory. Usual synthesizer is impossible to measure phase-errors when used same hardware and increasd hopping rate, becouse of hardware of phase detector is outer limit. In this paper, we will propose new frequency synthesizer which is able to hop in higher frequency. We improve usual method: (1) changing phase detector with new scheme, (2) design the digital circuit with parallel processing architecture in order to deal with higher hopping. |
