【摘要】：將傳統(tǒng)方法中偽隨機(jī)序列發(fā)生器與電光調(diào)制器產(chǎn)生的光偽隨機(jī)信號(hào),替換為光電振蕩器產(chǎn)生的光混沌信號(hào)。搭建光電振蕩器仿真系統(tǒng),產(chǎn)生帶寬為30GHz的光混沌信號(hào),利用1.25GHz低速模數(shù)轉(zhuǎn)換器,成功地對(duì)0~10GHz頻帶內(nèi)的5個(gè)頻率隨機(jī)、幅度隨機(jī)的頻域稀疏信號(hào)進(jìn)行壓縮采樣和信號(hào)重構(gòu),并對(duì)混沌光子壓縮采樣的重構(gòu)性能與傳統(tǒng)方法做出詳細(xì)比較。仿真結(jié)果表明,這種混沌光子壓縮采樣方法可行,且其重構(gòu)概率大于傳統(tǒng)方法。
[Abstract]:The optical pseudorandom signal generated by the pseudorandom sequence generator and electro-optic modulator in the traditional method is replaced by the optical chaotic signal generated by the optoelectronic oscillator.A simulation system of optoelectronic oscillator is built to generate optical chaotic signal with bandwidth of 30GHz. Using 1.25GHz low speed A / D converter, five random frequency and amplitude random frequency domain sparse signals in 0~10GHz frequency band are successfully compressed and sampled and the signals are reconstructed.The reconstruction performance of chaotic photon compression sampling is compared with traditional methods in detail.The simulation results show that the chaotic photon compression sampling method is feasible and its reconstruction probability is higher than that of the traditional method.
