Direct Detection and Coherent Optical Systems Employing Error-Correction Codin.

Abstract

We evaluate the bit error probability of coded lightwave systems employing direct detection with OOK modulation, and coherent systems with FSK modulation and noncoherent detection. Block codes, convolutional codes, and concatenated codes are investigated. For direct systems, both hard and soft decoding are considered. Only hard decoding is employed in coherent optical systems.
