摘要：
Multi Header-Hybrid Pulse Position Modulation (MH-HPPM) has been shown to be a better dimming controlled variant of Pulse Position Modulation (PPM) scheme for visible light communication (VLC) systems. In this paper, the spectral analysis of the MH-HPPM scheme is numerically analyzed and simulation results are presented. The paper also presents generation of MH-HPPM sequence using Labview NXG, probability distribution of ones and zeros in the MH-HPPM sequence for various dimming values. The spectral analysis shows that there are distinct spectral components corresponding to the frame rate and its associated harmonics.
