Abstract: In pulse shaping filters, parameters such as the roll-off factor and the symbol span, which determine the overall performance, are of great importance when implementing a real-time system due to limited hardware resources. In this paper, we experimentally investigate a multiband carrier-less amplitude and phase (<italic>m</italic>-CAP) visible light communications (VLC) system employing such filters and assess the link performance for a range of filter lengths and show the relationship between the system data rate (or spectral efficiency) and computational complexity. We show that lower order <italic>m</italic>-CAP can offer the same system performance as higher order systems while offering much lower computational complexity. By optimizing the filter parameters and the order m of an <italic>m</italic>-CAP VLC link, we achieve the largest improvement in the data rate and bandwidth efficiency of 9.69&x0025; and 40.43&x0025;, respectively, when compared with 2- and 8-CAP. We also show that the <italic>m</italic>-CAP VLC link with <inline-formula><tex-math notation="LaTeX"> m\geq 6</tex-math></inline-formula> can be designed with the same filter parameters to demonstrate a link with both the highest data rate and spectral efficiency simultaneously in contrast to lower order systems.
