WebbAmong these modulation techniques, we are going to compare the two, QAM and QPSK. The QPSK is very much similar to the PSK the only difference between PSK and QPSK is … WebbWe prove that the phase estimation process makes coherent QPSK more vulnerable than DQPSK to the XPM induced by 10G-OOK channels. A novel sensitivity penalty formula is presented and verified against simulations.
