Abstract :
In this paper the performance of optical fast frequency-hopping with forward error correction is evaluated. Beat noise is the main performance limitation for a low-complexity implementation using optical filtering of incoherent light. Taking the beat noise into account, we show how to improve the performance with channel coding and soft decoding optimized for this channel.
