In this letter, we propose an experimental demonstration of uplink visible light communications based on interleaved frequency division multiple access (IFDMA) with high spectral and power efficiencies, low complexity of the transmitter, high tolerance against multipath-induced distortion, and synchronization error. We show that IFDMA with a lower peak-to-average power ratio offers improved bit error...
We propose an uplink visible light communication (VLC) scheme based on interleaved frequency division multiple access (IFDMA), which provides some highly desirable features such as high spectral efficiency and high tolerance against multipath distortion. Compared with OFDMA, the IFDMA has lower PAPR and lower computation complexity at the transmitter. The experiment results show that the increased...
