【摘要】：为了有效克服传统电子信号发生器在工作带宽和工作频率方面存在的电子瓶颈,满足未来光载超宽带系统应用需要,提出了一种光子学超宽带(UWB)信号产生方法。基于微波光子微分的原理,该方法在光域中对高斯脉冲进行灵活处理,进而实现UWB信号的产生。通过理论推导和计算机仿真,对所提方法进行了分析与验证,结果表明,该方法可根据需要实现多种UWB信号波形的产生与调制。此外,通过对系统进行优化配置,还可在输出UWB信号的功率谱中引入一个频率可调的零点,从而避免UWB信号与现有WiFi信号之间的相互干扰。
[Abstract]:In order to overcome the electronic bottleneck of the traditional electronic signal generator in operating bandwidth and working frequency, and to meet the needs of the future application of optical ultra-wideband (UWB) system, a photonic ultra-wideband (UWB) signal generation method is proposed. Based on the principle of microwave photon differentiation, this method can process Gao Si pulse flexibly in optical domain, and then realize the generation of UWB signal. Through theoretical derivation and computer simulation, the proposed method is analyzed and verified. The results show that the method can generate and modulate various UWB signal waveforms according to the need. In addition, by optimizing the configuration of the system, a frequency adjustable zero point can be introduced into the power spectrum of the output UWB signal, thus avoiding the interference between the UWB signal and the existing WiFi signal.
