Abstract

Carrier-less amplitude and phase (CAP) modulation has recently been considered as an alternative to optical orthogonal-frequency-division-multiplexing (O-OFDM) in visible light communication (VLC) systems. The main advantages of CAP over O-OFDM are its lower implementation complexity at the transmitter side and its lower peak-to-average power ratio. Here, we consider CAP modulation where matched filtering and equalization at the receiver are performed in the frequency domain, resulting in reduced system complexity. Through numerical results we investigate the performance of this transmission scheme and, in particular, study the impact of the roll-off factor and the length of the pulse shaping filters.
