Multi-header pulse interval modulation (MH-PIM) for visible light communication system

Abstract

In this paper, a Multi-header Pulse Interval Modulation (MH-PIM) is presented for visible light communication. The paper discusses the fundamental principles of the symbol structure, its code properties, and slot error performance of the proposed scheme. Throughout the paper, the proposed scheme performance is analyzed and compared with PPM, DPIM, and DH-PIM in terms of average frame length, bandwidth requirement, and slot error performance. The system is simulated in MATLAB considering the channel adds white Gaussian noise and no interference is added from ambient light sources. It is verified from the result that MH-PIM has less average frame length, and requires less bandwidth and better slot error performance compared to other modulation schemes.
