Abstract :
The discrete cosine theorem (DCT)-based real-valued linear code is derived for the first time in the literature. A BCH-like subclass of DCT linear codes is also developed, for which fast decoding algorithms exist. It is shown that the DCT-based error control codes proposed by the authors can be viewed as a bridge to link the fields of source coding and channel coding.<>
