Transmitter comparison and unequal bit error probabilities in coherent QPSK systems
Paper in proceeding, 2007
We compare different QPSK transmitters and find that some simple configurations can give rise to a significant difference in BER between the two transmitted bits. The optimum receiver filter bandwidth is affected by this phenomenon. © 2006 Optical Society of America.
