摘要 通过研究相干光正交频分复用(CO-OFDM)系统中正交/同相(IQ)不平衡对系统性能的影响,提出一种新型IQ不平衡时域补偿TS(基于训练序列)算法,并与传统的时域格拉姆-施密特正交化(GSOP)算法进行了对比。 The effects of IQ imbalance on the coherent optical OFDM systems are discussed in this paper. A novel time-domain compensation algorithm based on training sequence is proposed which has a better advantage than the traditional GSOP algorithm.
