In modern telecommunication systems, FEC has been widely used. The emergence and development of this technology is the need of the telecommunication system itself. In the engineering practice, the ideal digital channel does not exist, which results from distortion and non-isochronous delay. Such result means generating error and jitter, which finally can be reflected in the error code of the system. Adopting FEC technology is to improve the error code more efficiently, and such technology can be realized by hardware as well as software. Therefore, we will introduce some relevant knowledge in this article, ranging from its principle, how it works, to different types and its applications. This paper interprets the principle and types of FEC and also gives some examples of FECs and their applications. It evaluates research work and discusses about the security of FECs in the end.
