ULTRA WIDEBAND COMMUNICATION SYSTEM, TRANSMISSION DEVICE, RECEPTION DEVICE, AND RELAY DEVICE USED FOR THE SAME

摘要

An ultra wideband communication system includes: a pulse generation unit for generating a pulse signal according to a data signal; a first optical phase modulation unit for subjecting the pulse signal to optical phase modulation and outputting it as an optical pulse signal; an optical transmission path for transmitting the optical pulse signal; a template generation unit for outputting a template signal; a second optical phase modulation unit for subjecting the optical pulse signal to optical phase modulation according to the template signal and outputting it as an optical phase demodulated signal; an optical phase intensity conversion unit for modifying the information associated with the optical phase of the optical phase demodulated signal into information associated with the light intensity and outputting is as an optical correlation signal; a photoelectric conversion unit for photo-electrically converting the optical correlation signal and outputting it as a correlation signal; and a signal identification unit for detecting a data signal by identifying the correlation signal outputted from the photoelectric conversion unit.
