摘要
超宽带射频识别(UWB-RFID)的调制信号需满足规定的频谱辐射掩蔽,介绍超宽带射频识别的基本原理,分析跳时脉冲位调制(TH-PPM)的原理;研究源脉冲高斯波形的能量谱密度特性,提出一种线性组合迭代算法,由该算法合成源脉冲,验证该脉冲合成算法是可行的。
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.
