摘要

In this article, we present proof-of-concept of M-ary asymmetrically clipped (AC)-frequency-shift keying (FSK) for energy-efficient/low data rate visible light communications (VLC). M-ary AC-FSK uses the odd frequency waveforms from 2M-ary FSK; which exhibit half-wave symmetry. Owing to this half-wave symmetry, the negative amplitude excursions are clipped without loss of information. Hereby, we i...
