Abstract
AbstractPulse‐position modulation (PPM) schemes are usually used in optical communication systems to improve the receiver sensitivity. Recently, multi‐PPM (MPPM) signaling [1] has been presented as a very powerful alternative to the PPM format, for laser direct detection systems. With similar information efficiency, it achieved a significant performance improvement at higher transmission rates, and had less bandwidth expansion, and better peak‐to‐average power ratios, with respect to the PPM model. In this article we investigate extending the MPPM signaling to coherent optical communication systems. © 1995 John Wiley & Sons, Inc.
