【摘要】:為了有效克服傳統(tǒng)電子信號發(fā)生器在工作帶寬和工作頻率方面存在的電子瓶頸,滿足未來光載超寬帶系統(tǒng)應用需要,提出了一種光子學超寬帶(UWB)信號產(chǎn)生方法;谖⒉ü庾游⒎值脑,該方法在光域中對高斯脈沖進行靈活處理,進而實現(xiàn)UWB信號的產(chǎn)生。通過理論推導和計算機仿真,對所提方法進行了分析與驗證,結果表明,該方法可根據(jù)需要實現(xiàn)多種UWB信號波形的產(chǎn)生與調制。此外,通過對系統(tǒng)進行優(yōu)化配置,還可在輸出UWB信號的功率譜中引入一個頻率可調的零點,從而避免UWB信號與現(xiàn)有WiFi信號之間的相互干擾。
[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.
