【摘要】：将传统方法中伪随机序列发生器与电光调制器产生的光伪随机信号,替换为光电振荡器产生的光混沌信号。搭建光电振荡器仿真系统,产生带宽为30GHz的光混沌信号,利用1.25GHz低速模数转换器,成功地对0~10GHz频带内的5个频率随机、幅度随机的频域稀疏信号进行压缩采样和信号重构,并对混沌光子压缩采样的重构性能与传统方法做出详细比较。仿真结果表明,这种混沌光子压缩采样方法可行,且其重构概率大于传统方法。
[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.
