DEVICE AND METHOD FOR GENERATING CHAOTIC SIGNAL

摘要

A chaos signal generating apparatus and method are provided to solve a problem of the related art that when value of a passive element is changed by a certain degree according to a change in a process, a chaos signal may not be generated at a UWB(Ultra Wide Band) operation frequency. A PN(Pseudo Noise) signal generating unit(51) is configured in a digital logic type and generates a pseudo-random signal in a digital form with a certain frequency. A VCO(Voltage Control Oscillator)(52) generates a clock signal of a certain frequency. A mixer unit(53) mixes the pseudo-random signal with the clock signal to generate a chaos signal and output it. A BPF(Band Pass Filter)(54) filters the chaos signal outputted from the mixer unit(53) so as to become a chaos signal of a desired band and outputs it.
