Abstract

Carrierless amplitude and phase modulation technique (CAP) has been widely employed in visible light communication (VLC) due to its simple transceiver. While the simplicity of CAP receiver results in the elimination of carrier recovery, it also leads to significant increase in CAP sensitivity to timing jitter. In this work, a correlation-based synchronization algorithm whose synchronization sequence is obtained from the CAP pulse shaping filter has been proposed for a joint bit and frame synchronization at the CAP receiver. The performance of the proposed ‘CAP-filter’ synchronization sequence is evaluated with both theoretical and simulation analysis. It is shown that the proposed ‘CAP-filter’ algorithm achieved perfect synchronization with a BER performance matching that of CAP with no jitter. This performance is reported for both low and high constellation order and in all the SNR regimes considered. Finally, the viability of the ‘CAP-filter’ synchronization algorithm in VLC systems is demonstrated through laboratory experiment.
