摘要
对大啁啾相位模板附加小啁啾的来源进行了分析与推导,提出了相位补偿方案.基于相位补偿法,分析了实现的高平坦大啁啾梳状滤波器;通过改变光源阵列波长间隔与偏振态提出了一种传输长度可变、码字可调、一致性较好的UWB网络通信的实现方案.通过仿真,实现了相位编码个数为4、不同码字的monocycle信号与doublet信号产生.
The additional chirp introduced by large chirped phase mask is analyzed and calculated, then a phase compensation method is proposed. Based on phase compensation method, high flattened comb filter is realized and analyzed. A reeonfigurable multi-user UWB network communication scheme is proposed by changing optical source array wavelength spacing and polarization state. Four-chip, biphase-coding monoeyele and doublet signals with dif- ferent code patterns are generated by simulation.
