    There are many modulation methods suitable for optical wireless communication.OOK,the earliest modulation scheme,was widely used for its simplicity,but compared with PPM its power efficiency is lower.PPM has hence replaced OOK and been adopted widely in optical wireless communication for its high average-power-efficiency.DPPM and DPIM are two new modulation methods for optical wireless communication,which may be the substitutes of PPM because of their better performance in power efficiency and bandwidth efficiency.The performance of the modulation schemes(OOK,PPM,DPPM and DPIM)are analyzed and comparison of their power efficiency,bandwidth efficiency,transmission capacity and their resistance to ISI is also made in this paper.
