Reed-Solomon Hybrid Codes for Optical Communications

Abstract

The astonishing performance of concatenated codes attracted many researchers and this has resulted in an explosive amount of literature since their introduction few years ago. As concatenation between codes did not actually arise from applying a pre-existing theory, most of their outstanding features remain to be explained. This paper gives some explanation of the concatenation between Reed Solomon (RS) code and convolutional code. The aim of this work is to evaluate the performance of serial and hybrid concatenated convolutional and RS codes in optical communication. We consider the on-off keying (OOK) modulation and LOG MAP algorithms with iterative decoding.
