Multiplier-free realtime phase tracking in digital synchronous QPSK receiver for coherent optical detection

A multiplier-free phase estimation algorithm based on the barycentre approach for coherent QPSK detection is presented. A selectivity mechanism was developed that significantly improved its performance. In addition to recently published measurement results, theoretical background and new simulation results are presented.
