Paper Abstract

In the optical wireless communications systems, modulation schemes such as PPM, DPPM are often used because of its power efficiency. This paper presents a modified DPPM modulation technique for optical wireless communication. We study the properties of IDPPM and compare the power and bandwidth efficiency of OOK, PPM, DPPM and IDPPM. Also we analyse the packet-error probability on ideal distortionless channels with AWGN and examine the detection technology of the system. Finally we show the improving of performance using IDPPM modulation.
