摘　　要：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 applications, an experimental impulse radio UWB communication system is designed. At the transmitting terminal, a UWB pulse is generated based on avalanche transistor; and at the receiving terminal, UWB pulse’s detecting and receiving is achieved by the use of high-speed comparator. These works are imitated by Multisim 11.0, manufactured and measured. 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; at the receiving terminal, the circuit can get well performance of detecting UWB pulse signal.
