چکیده
Intensity modulation with direct modulation (IM/DD) favors low duty cycle modulation schemes such as pulse position modulation (PPM) and multiple PPM(MPPM).In this paper,the channel model over IM/DD is introduced. Then, a brief summary is given about some of the modulation techniques used in this area. Finally, some of the pulse position based coded modulation techniques are rewiewed.
