Abstract
The present invention discloses a QPSK signal conjugate relationship identification method and apparatus. The method includes: receiving a first binary sequence signal, using the first binary sequence signal to modulate an optical signal, and determining, within a first predetermined range, a first bias voltage in a QPSK modulator; receiving a second binary sequence signal, using the second binary sequence signal to modulate the optical signal, determining a second range within the first predetermined range according to the first bias voltage, and determining, within the second range, a second bias voltage in the QPSK modulator; and determining a conjugate relationship of the QPSK signal according to a value relationship between the first bias voltage and the second bias voltage. The present invention features low costs and a small component size.
