针对超宽带通信的应用特点,设计了一个IR-UWB通信实验系统,在发射端采用雪崩三极管产生超宽带窄脉冲,在接收端利用高速比较器实现超宽带窄脉冲的检测接收,并应用Multisim 11.0对两部分进行仿真,且通过制作实物电路进行性能测试和验证.测试结果表明,发射端产生的脉冲信号波形良好,基本形状符合超宽带要求；接收端电路也能取得较好的超宽带脉冲检测效果.%Aimed at the characteristic of UWB communication applications, an experimental impulse radio UWB communication system is designed. At the transmitting terminal, a UWB pulse is generated based on avalanche transistor, while al the receiving terminal, UWB pulse's detecting and receiving is achieved by the use of high-speed comparator. These works are simulated, manufactured and measured by Multisim 11. 0. The measured results show that, at the transmitting terminal, the generated pulse signal has a good waveform, which basically satisfies with the request of UWB, and at the receiving terminal, the circuit can get well performance of detecting UWB pulse signal.
