Abstract:
1. An impulse radio-based ultra wideband communication system using an ultra wideband impulse and a 1-bit digital sampler, comprising: a transmitting RF module comprising an integrated impulse generator capable of implementing on-off-keying modulation or pulse position modulation, and an amplifier for amplifying output of the integrated impulse generator; a receiving RF module comprising a two stage envelope detector for detecting an envelope of a received signal and a comparator for converting the detected signal into a rectangular pulse; a digital signal recovery unit for restoring the signal from the receiving RF module to a digital signal using the 1-bit digital sampler; a transmitting signal processor for impulse modulation or pulse mapping; a receiving signal processor for synchronizing the digital signal and tracking symbol synchronization; and an ultra wideband antenna for transmitting and receiving an ultra wideband impulse signal.
