| 摘 要： | 将高阶循环累积量引入基于正交频分复用(OFDM)的弹性光网络(EON)的调制格式识别中。通 过计算OFDM信号不同调制格式(BPSK、QPSK、16QAM和64QAM)的高阶循环累积量,给 出了OFDM-EON信号不同调制格式的识别阈值区间,并采用仿真方法验证了该区间的 识别准确率。结果表明,利用所提出的识别阈值区间,对波特率为28G的OFDM-EON信号(各 子载波随机设置调制格式)进行调制格式识别,在光信噪比(OSNR)为34dB时,子载波调制格式的识别准确率可达到100%。

| Abstract: | In this paper,the high-order cyclic cumulants are firstly a pplied to the modulation formats identification in Orthogonal frequency division multiplexing (OFDM)-based elast ic optical networking (EON) under the condition of lack of prior information.By calculating the high-order cyclic cumulants of different modulation formats (BP SK,QPSK,16QAM and 64QAM) for OFDM-based EON signals,we propose the identification threshold interval of OFDM -based EON signals with different modulation formats,and verify the identification accuracy by simulation.When t he sub-carriers are modulated randomly by different modulation formats,the identification accuracy for OFDM- based EON signal reaches 100% by using the proposed identification threshold interval with OSNR of 34dB and baud-rate of 28G. |
