Paper Abstract

Carrier-less amplitude and phase (CAP) modulation schemes have been actively explored in visible light communication (VLC) because of its high spectral efficiency and simpler transceiver design. Conventionally, CAP with root-raised-cosine filter (CAP-RRC) has been explored for VLC. However, in this paper, we have implemented CAP with a Gaussian minimum shift keying filter (CAP-GMSK) in order to improve the system performance. The proposed scheme is compared against CAP-RRC and baseline DCO-OFDM, on the basis of symbol error rate (SER) and peak-to-average power ratio (PAPR) performance. The result shows that as compared to DCO- OFDM, CAP-GMSK and CAP-RRC provides a SNR gain of 8 and 1 dB and PAPR improvement of 2.5 and 2.3 dB respectively.
