Abstract :
A chromatic dispersion insensitive demodulation for real-valued signals (e.g. binary shift keying and 4 amplitude shift keying) is proposed. This method utilises the symmetric spectrum of the signals and can be implemented simply in feed-forward manner. Its feasibility is confirmed by simulations and experiments.
