| Abstract: | The modulated signals of ultra-wideband RFID must meet the requirements of emission mark.The principle of UWB-RFID was presented,and the time-hopping pulse position modulation was analyzed.The characteristic of Gaussian impulse and its power spectrum density was studied to propose an iterative linear combination algorithm.Composing the source pulse with this algorithm verified the feasibility of this algorithm. |
