UWB wireless transmitter and receiver using UWB linear FM signals and method thereof

摘要

An ultra wideband (UWB) wireless transmitter includes a first pulse generator for modulating data to be transmitted and outputting a first linear modulated signal, a second pulse generator for modulating the data to be transmitted and outputting a second linear modulated signal, an adder for adding the first and the second linear modulated signals, a pulse shaper for shaping the signal output from the adder, a carrier generator for outputting a carrier, a mixer for mixing the signal output from the pulse shaper with the carrier, a transmission unit for transmitting the signal output from the mixer, and a controller for controlling the modulation of the signal to be transmitted by controlling the operation of the first and the second pulse generators and the carrier generator. As a result, a data transmission rate can be greatly increased with very little inter-pulse interference even when the pulse intervals are reduced.
