Error Detection and Correction for Coding Schemes
Coding techniques are used for several reasons: reduction of dc (direct current) wandering, suppression of intersymbol interference, and self-clocking capability. These problems are of engineering interest in the transmission of digital data. Error correction and error detection coding—collectively called error control coding—is the means whereby errors introduced into transmitted data can be detected and corrected at the receiver.
The coding schemes discussed in this chapter are for error detection and correction, specifically forward error correction (FEC) techniques. FEC codes may be divided into two classes of codes: linear block codes and convolutional codes [1]. Depending on the intended ...
