Abstract
A wireless impulse transmitter that is for transmitting pulse trains to a plurality of receivers, includes a pulse selector, a pulse supplier, and a transmission unit. The pulse selector is for selecting, from a plurality of orthogonal pulse shapes assigned in a two-to-one correspondence with the receivers, pulse shapes corresponding to symbols of an input data stream. Each of the two pulse shapes assigned to each receiver represents either one or zero to the corresponding receiver. The pulse supplier is for supplying pulses in pulse shapes selected by the pulse selector. The transmission unit is for transmitting the pulses supplied from the pulse supplier in pulse trains, wherein pulses with pulse shapes assigned to different receivers are transmitted simultaneously.
