UWB wireless transmitter and receiver using UWB linear FM signals having opposite slopes and method thereof

摘要

A second pulse generator, UWB wireless transmitter according to the present invention modulates the first pulse generator, the data to be transmitted and outputting a first linear modulated signal by modulating the data to be transmitted and outputting a second linear modulated signal, a first linear modulated signal and the second linear loading a carrier generator, a signal output from the pulse shaper to the modulation signal adder, outputs of shaping the signal output from the adder pulse shaper, a carrier wave to be added to the carrier mixer, and transmits the signal output from the mixer in that the transmitter and the first pulse generator, a second operation of the pulse generator and control carrier wave generator and a controller for controlling the modulation of the signal to be transmitted. The pulse intervals without mutual interference between the turn down pulse, it is possible to increase the amount of data transfer, the other network is superimposed under the multi-piconet environment, even if required a band drop, linear frequency modulation is different from linear frequency modulation scheme used by the other network, by using a reduced interference it may increase communication efficiency.
