Paper Abstract

This article present several possible implementations for an optical square 16-QAM transmitter structures. Two efficient carrier phase estimation techniques with feed-forward structure have been tested in a real-time transmission and compared with each other to present the influence of phase noise; Blind Phase Search (BPS) and QPSK partitioning. 2.5 Gbit/s synchronous coherent 16-QAM data is transmitted and received in a real-time heterodyne setup with BER below FEC (7% overhead) threshold.
