We examine how image coding schemes can be designed for noisy channels such as radio links, cordless telephones or mobile communications. We start with a JPEG based scheme and discuss its performance over channels with random and burst errors. We propose a number of modifications to the JPEG scheme including: avoiding DPCM coding of the DC coefficients; using a highly protected short header, the error resilient entropy code (EREC), error concealment and a wavelet transform. We show that these methods can improve the error resilience, without any significant increase of bit rate or loss of error free picture quality.<>
