Enhanced Asymmetrically Clipped Optical ODFM for High Spectral Efficiency and Sensitivity

Not Accessible

Your library or personal account may give you access

Abstract

Using ‘musical’ chords at octaves, EACO-OFDM increases ACO-OFDM’s spectral efficiency to 87.5% of DC-biased OFDM, while providing a 7-dB SNR advantage for the same optical power. Nonlinear methods and matched filtering provide near theoretical performance.
