摘要 差分预编码器是光差分相移键控调制(DQPSK)中的重要组成部分.不同的光DQPSK调制方式和接收模型需要不同的差分预编码器.现有的光DQPSK传输实验往往忽略了预编码器的设计实现.通过研究光DQPSK的调制方式和接收模型,可以得出一种用来推导DQPSK预编码器逻辑表达式的方法.使用该方法,可以根据光DQPSK的调制方式和接收模型,设计相应的预编码器. Based on the study of several optical DQPSK encoders and decoders, a method for deducing the logic operational expression of the DQPSK precoder was proposed. Using this method, the logic operational equations of different DQPSK precoders corresponding to different encoders and decoders were given.
