• A simple, economical, and applicable spectrum equalization method is implemented by employing a reshaping filter combined in frequency-shift-keying/amplitude-shift-keying modulation scheme, to improve the quality of amplitude-shift-keying optical signal. 2.39 dB improvement of Q factor is experimentally demonstrated.
