The VLC technology leverages existing lighting fixtures to provide wireless data communication, which makes it attractive for many applications. However, the commercially available white LEDs that are predominantly employed in VLC offer low modulation bandwidths that limit the achievable data rate. Thus, CAP modulation is employed to improve achievable data rate, primarily due to its implementation simplicity and high spectral efficiency. The CAP scheme also has a special feature in that it can be implemented as a single band or a multiband scheme which provides design flexibility. This paper presents an in-depth study of the implementation of CAP in LED-based VLC systems, highlighting the unique features that make it specially suited for VLC applications. Furthermore, a comprehensive investigation is carried out regarding the design parameters of the CAP modulation transceiver, its benefits and techniques to mitigate the challenges of CAP-based VLC systems. date: 2018 date_type: published official_url: http://doi.org/10.1109/ACCESS.2018.2876001 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1600016 doi: 10.1109/ACCESS.2018.2876001 lyricists_name: Haigh, Paul lyricists_id: PAHAI28 actors_name: Bracey, Alan actors_id: ABBRA90 actors_role: owner full_text_status: public publication: IEEE Access volume: 6 pagerange: 60532-60546 issn: 2169-3536 citation: Akande, KO; Haigh, PA; Popoola, WO; (2018) On the Implementation of Carrierless Amplitude and Phase Modulation in Visible Light Communication.
