Abstract :
An approach to combined source-channel coding is presented. The method applies to a scalar source encoder designed using the Lloyd-Max algorithm and uses a family of binary primitive BCH codes. The channel model used is the binary symmetric channel. A variety of experimental results are presented which illustrate the average signal-to-noise ratio gain possible over no channel coding when different numbers of source encoder output bits are protected and the overall rate is held fixed. A number of interesting conclusions are drawn which can prove helpful in attempting to match existing source and channel coding techniques
