UWB通信系统中TH_PPM调制的硬件仿真实现

超宽带(UWB)技术具有功耗低、抗干扰和抗多径能力好、穿透能力强等优点,特别适用于隐藏活动目标检测和近距离数据传输。对超宽带通信中最常用的TH_PPM调制方式从信号产生到方案设计实现进行了分析,将所设计的VHDL程序用Modelsim硬件仿真软件进行了功能仿真,并将程序下载到芯片上用示波器进行了波形实测,结果完全满足设计要求。

Hardware simulation of TH_PPM in UWB communication system

Because of its low power consumption,good ability of anti-multiple-path and good penetrating ability, UWB is used in data transmission and hidden target detection. The article introduces the most commonly used TH_PPM modulaton signals from design to achieve in UWB communication system. Then,the designed VHDL programes is been functional simulated by Modelsim hardware simulation software.We use oscillograph to test waves and the result shows the design has achived demonds we expected before.
