SUPER-BROADBAND WIRELESS TRANSMITTER, SUPER-BROADBAND WIRELESS RECEIVER, AND SUPER-BROADBAND WIRELESS TRANSMITTER/RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a technology for facilitating implementation of a UWB system using a chirp signal.;SOLUTION: Digital data consisting of at least 2 bits is input to a chirp modulation section 12, a selection is made between a frequency variable range of frequency f₁-f₂ and a frequency variable range of frequency f₂-f₃ based on one bit, and a selection is made between sweep in the direction of increasing the frequency and sweep in the direction of decreasing the frequency in a selected frequency variable range based on the other bit.;COPYRIGHT: (C)2009,JPO&INPIT
