Patent attributes
An impulse wireless communication system includes an oscillation signal generator that generates a plurality of oscillation signals having a delay interval with each other and having the same phase and amplitude or different phases and amplitudes, an envelope signal generator that extracts a sync signal and a data signal making up communication signal data and generates an envelope signal for the sync signal and an envelope signal for the data signal, a signal synthesizer that synthesizes the plurality of oscillation signals with the envelope signals, an envelope signal extractor that extracts a plurality of modulation envelope signals from the impulse signal, an amplitude phase determiner that determines the phase and the amplitude in the plurality of modulation envelope signals based on the plurality of oscillation signals, and a calculator that extracts the envelope signals from the plurality of modulation envelope signals based on the phase and the amplitude.
