In the modern broadband communication network, due to the growth of internet traffic together with an increase in a bandwidth and range of new services, both wire and wireless communication systems are rapidly evolving to support high transmission data rate. Especially, fiber-optic communication systems as a back-bone communication network, are now developing the 100-Gb/s transmission system. And the optical transport systems are further expected to reach up to 1-Tb/s within a decade. Wireless high-speed nearby communication represented by wireless personal area network (WPAN) technology, are also developing to support high data rate applications such as video on demand (VoD), high-definition television (HDTV) and 3D-videos. In this trend, high performance forward error correction (FEC) architecture which is essential in communication systems are required to support high-throughput and low-power consumption.
In this thesis, I present efficient FEC architectures for various communicatio
