N2 - The use of a wide variety of modulation schemes for visible light communications (VLC) systems has been proposed since the birth of this field, and each of these modulations address some specifications that must be met by the system. Modified Hermite pulses define a family of functions with desirable characteristics regarding their orthogonality and time-frequency behaviour that has been used previously in radio-frequency and ultra wideband communications, ranging and VLC applications. In this work, the first experimental evaluation, to the best of authors’ knowledge, of an Hermite function-based multicarrier scheme for VLC is presented and compared with simulations carried out under similar conditions. The results show that, for low modulation orders, the system is able to detect signals even below the noise floor.
