Abstract
In this paper a new digital pulse time modulation scheme known as Multilevel Digital Pulse Interval Modulation (MDPIM), which is suitable for optical wireless communication systems, is introduced and its properties are investigated. Mathematical expressions for MDPIM signal, its bandwidth and transmission rate are derived, whereas its power spectral density (PSD) and the slot error rate performance are simulated. The performance of the proposed modulation scheme is analysed for different bit resolutions and the results are compared with other pulse modulation techniques such as PPM, DPIM and DH-PIM.
