Document Type and Number:
Japanese Patent JP2006115150
Kind Code:
A
Abstract:
To provide a wireless communication system that is simplified by omitting a circuit required for the use of a carrier.
A wireless transmitter includes: a signal conversion section 1 for converting a data signal to be transmitted into a signal S1 whose state transits in accordance with a logical value of the data signal; a rectangular wave signal generating section 2 for generating a rectangular wave signal S2 synchronously with the state transition of the signal S1; and a transmission antenna 3 for transmitting the rectangular wave signal S2, the center frequency of the transmission antenna 3 is set in matching with an odd number multiple of a frequency with 2T as one cycle, wherein T is a pulse width of the rectangular wave signal S2.
