I am doing DP-QPSK simulation. sequence length is 8192, samples per bit is 32. so we can get 262144 samples.after coherent detection with “Optical Coherent DP PSK/QAM Receiver” block, the output X and Y components are connected to two constellations. I found there are only 8192 symbols in constellation. How the Optisystem to do that? as I understand, it should be done using mean or downsample or resample functions like in Matlab. is it correct?
