    • A signal generating method and apparatus in the field of signal technologies are provided. The method includes: adjusting an incident angle of an optical signal entering a polarization beam splitter, so that the polarization beam splitter outputs a first optical signal and a second optical signal that have a preset power ratio; performing QPSK modulation on the first and second optical signal respectively by using a first and second externally input data streams, to obtain a first and a second QPSK optical signal; before the first QPSK optical signal and the second QPSK optical signal are input into a polarization beam combiner, adjusting a polarization state of the first or the second QPSK optical signal; when the polarization states of the two QPSK optical signals are the same, outputting a 16QAM signal; and when the polarization states of the two QPSK optical signals are orthogonal, outputting a DP-QPSK signal.
    • 提供了信号技术领域的信号产生方法和装置。 该方法包括:调整进入偏振分束器的光信号的入射角,使得偏振分束器输出具有预设功率比的第一光信号和第二光信号; 通过使用第一和第二外部输入数据流分别对第一和第二光信号执行QPSK调制,以获得第一和第二QPSK光信号; 在将第一QPSK光信号和第二QPSK光信号输入到偏振光束组合器之前,调整第一或第二QPSK光信号的偏振状态; 当两个QPSK光信号的极化状态相同时,输出16QAM信号; 并且当两个QPSK光信号的偏振态正交时,输出DP-QPSK信号。
