Abstract

In the field of visible light communication (VLC) systems, carrier-less amplitude and phase modulation have lately been explored as an alternative to various modulation techniques, especially optical orthogonal-frequency-division-multiplexing. This study simulates the performance of carrier-less amplitude phase (CAP) modulation compared to basic On-Off Keying in terms of bit-error-rate, constellation diagram and eye diagram. The performance of CAP-2, CAP -4 and CAP-8 was considered in this study due to low computational complexity. Based on various modulation orders of CAP signals, CAP-4 has the lowest EVM (-10.90 dB) and highest MER (11.30 dB) which indicates better performance, supported by good eye diagram representation. Non-square constellation diagram limits the performance of CAP-8 scheme
