Coded Modulation for Fiber-optical Communication Systems with Optical Amplifiers

(Professor Joseph M. Kahn)

In this project, we investigate the effect of using multilevel signaling with coded modulation techniques for fiber-optical communication systems with optical amplifiers. Such systems are usually dominated by the beat noise of amplified spontaneous emission. After square-root transforming the received signal, we apply the coded modulation schemes such as trellis-coded modulation and multi-level coding, which lead to significant power gain. Further improvements are made by jointly optimizing the coded modulation and the signal constellation.
