Title:
METHOD AND CIRCUIT DEVICE FOR WIRELESS DATA TRANSMISSION BETWEEN BASE STATION AND ONE OR A PLURALITY OF TRANSPONDERS
Document Type and Number:
Japanese Patent JP2005223917
Kind Code:
A
Abstract:
To provide a method and a circuit device for wireless data transmission and thereby enables the improved utilization of a bandwidth, wherein a relatively high transmission rate can be used, and achieve a large transmission reaching range.
In this method, a modulation signal during a modulation period is a noise signal, and in this circuit device, a modulation signal generating unit is so formed that it generates the noise signal as the modulation signal.
