Abstract
In recent literature digital PPM has been shown to be an effective modulation format for optical communication channels. In this paper the authors show how Reed-Solomon codes, used in conjunction with digital PPM, can further improve receiver sensitivity. They present computer predicted results, at a bit-rate of 565 Mbit/s and a wavelength of 1.5 μm, comparing both uncoded and coded homodyne digital PPM with coherent PCM. It is concluded that the Reed-Solomon coded system offers an improvement of 4 dB over the uncoded system and 9 dB over homodyne PSK PCM
