Abstract:
In this article 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 16-QAM data was achieved in a field-programmable gate array (FPGA) based coherent receiver.
