Signal Constellation Design for Optical Intensity Modulated Channels

Abstract

We define lattice codes for the optical intensity, direct-detection channel. These codes obey a non-negativity constraint and are shaped to minimize average optical power. Expressions for the coding and shaping gain of such codes over a rectangular PAM baseline are presented. Over short distances, we show that lattice codes provide significant rate gains for free-space optical links.
