Impact of transmitter and receiver imperfections on the performance of coherent optical QPSK communication systems

We investigate transmitter and receiver imperfections in coherent QPSK systems, and how their impact can be mitigated using DSP algorithms. Quadrature imbalance was found to be a particularly significant effect that will require compensation.
