WIRELESS IMPULSE TRANSMITTER, WIRELESS IMPULSE RECEIVER AND TRANSMISSION METHOD IN UWB-IR SYSTEM

摘要

A wireless impulse transmitter, a wireless impulse receiver and a transmission method in an UWB-IR system are provided to obtain a space-diversity gain always without the time-invariant condition of a wireless channel. A wireless impulse transmitter in an UWB-IR system comprises the followings: a data unit(110) in which data is stored; a space-shape coding unit(120) which processes the first single pulse string, set correspondingly to one data, through the PPM to express the data as information bit 0 or 1, and then codes/outputs the first single pulse string based on the space-shape diversity; and a multi-transmission antenna part(130) which transmits the coded signal.
