Abstract

In coherent optical communication QPSK system, an improved two-stage phase estimation algorithm is proposed to improve the estimation accuracy of carrier phase recovery, The BER simulation results compared with other schemes verify the feasibility of the algorithm. FPGA design adopts parallel design scheme. Simulation results compared with MATLAB verify the feasibility of the parallel design
