Abstract
This paper presents a comparison of the performance of optical communication links employing analog pulse-position modulation and analog intensity modulation. In particular, the theoretical output signal-to-noise ratios for the two types of modulation are compared assuming "equivalent" optical links. Analog pulse-position modulation offers signal-to-noise ratio improvement over intensity modulation at the expense of increased system complexity and expanded transmission band-width. The effect of timing errors on the signal-to-noise ratio of the pulse-position modulation receiver is considered, and it is shown that these errors can degrade performance significantly from theoretical .
