The simulation file for help
Hi I’m Wenhui Feng.I created a simulation file, there are about 100 gb/s PM-QPSK modulation communication system.But the result of simulation is not the result of theory, signal coming out in DSP, observed on the constellation diagram should be distributed in four quadrants, but I can’t do that, is my wrong parameters, or am I the simulation components put wrong file?
Can someone help me to modify it? Thank you very much, I really need to complete the simulation.
