Abstract :
Quad-Carrier QPSK-OFDM signal transmission and reception is successfully demonstrated with blind equalization like a 25-QAM signal with CMMA equalization. The phase recovery can be realized with simple Viterbi algorithm and the FOE should be done after 4 subcarriers are separated with FFT. 48-Gbit/s Quad-Carrier QPSK-OFDM signal is successfully transmitted over 80-km SMF-28 without penalty.
