摘　　要：UWB(Ultra Wide-Band)无线通信技术是一种基于直接发射窄脉冲的新技术,因其具有低功耗、良好的抗干扰和抗多径能力、穿透性能好等特点,特别适用于隐藏动目标检测和近距离数据传输,具有广泛的应用前景。对比超宽带多种调制解调方式,选取了脉冲位置调制。介绍了使用Verilog语言,在FPGA上实现PPM(Pulse Position Modulation)调制解调器,实现了对UWB窄脉冲的基带调制。The UWB（ Ultra Wide-Band）wireless communication technology is a new technology based on the nano-second width pulse. Owing to its low power consumption, good anti-interference and anti-multiple-path ability, and good penetrating ability, it finds wide applications in short-distance data transfer and hidden target detection. Based on a comparison of various Modulators and Demodulators, PPM （ Pulse Position Modulation） is chosen. A Pulse Position modulator is realized on FPGA using Verilog languages for the base signal modulation of UWB narrow pulses.
