The link bandwidth is given as unity, while the filter cut-off frequency is set to 0.1. The number of bands, or subcarriers, is selected as m = 1, 2, 5 and 10. Here, we show that under such a high bandwidth constraint, using m = 10 subcarriers can result in 40% and 17% improvement in bit rate compared to m = 1 and 2, and m = 5 subcarriers, respectively for the same BER target.eninfo:eu-repo/semantics/closedAccessCarrier-LessAmplitude And Phase ModulationVisible Light CommunicationsConference Object10.1109/WCSP.2015.73413382-s2.0-84975743739
