Simulation on Concatenated Code of Optical Communication System

With the development of optical communication technology for longer distance,greater capacity and higher speed,it is necessary to study deeply the better code type of FEC.In many code types of FEC applied in optical communication,the concatenated code with the complexity of short-length code and the performance of long-length code,is of extremely strong ability for burst and random errors,and has become the main research object of high-performance codes in optical communication system.This paper gives a theoretical analysis and describes the modeling and simulation of the RS-BCH concatenated code,and the result shows that,as compared with the cyclic code,the concatenated code is of high correction performance,moderate redundancy and easy implementation,and more suitable for the high-speed optical communication system.
