Nonlinear effect of IQ modulator in a realtime synchronous 16-QAM transmission system

Nonlinear effect of IQ modulator in a realtime synchronous 16-QAM transmission system

Different operation points of a 16-QAM modulator are tested in realtime. An optimal condition is found which minimizes BER. The FEC threshold was reached for a receiver input power below -30 dBm.
