Abstract

A joint source-channel coding scheme for the transmission of images over noisy channels is proposed. In this scheme, the interaction between source coding and channel coding is through a small number of parameters. A robust source coder based on the classification of the Discrete Wavelet Transform (DWT) coefficients of the image is coupled with a flexible error control scheme which uses a bank of channel codes. Robustness in the source coder is achieved by scalar quantization of the coefficients followed by robust arithmetic coding to check catastrophic propagation of errors. Robust arithmetic coding generates a sequence of equal-length packets of bits along with a small number of sensitive bits for synchronization.
