Impact of Iterative Decoding Techniques on the Reliability of Communications in Optical Transmission

Abstract

With the fast-paced advancement of communication technologies, there is an increasing demand for higher bandwidth, stronger reliability, and greater resilience. Although optical transmission offers excellent efficiency, it is still prone to certain performance issues. This paper investigates how iterative decoding methods—especially turbo codes and LDPC codes—can enhance the reliability of optical communication systems. It outlines the basic concepts, highlights the strengths and limitations of each technique, and discusses future directions. A comparative simulation is also included to demonstrate their practical effectiveness.
