ALIGNMENT OF IN-PHASE AND QUADRATURE DATA IN QUADRATURE PHASE SHIFT KEYING OPTICAL TRANSMITTERS |
摘要 |
<p>l/Q data skew in a QPSK modulator may be detected by sending identical or complementary data streams to I and Q channel PSK modulators, setting the relative carrier phase between I and Q to zero or p, and monitoring the average QPSK output power, where the data streams sent to the I and Q channels include streams of alternating ones and zeroes.</p> |
