IMPACT OF CHANNEL ERRORS ON DATA COMPRESSION

Abstract

This paper will present the relationship between the distortion of compressed data to the bit error rate on the channel. In most studies of data compression techniques, the communication channel is assumed to be error-free. Under this assumption, smaller distortions are generally achieved with more complex data compression techniques. Likewise, from the mathematical theory of data compression known as rate distortion theory, it is known that the minimum possible average distortion of data compression systems can be approached as the complexity or size of the source code increases.
