Abstract :
An image compression and channel coding scheme is proposed for efficient image transmission over mobile radio channels. The image-compression system is based on a wavelet representation coupled with the JPEG baseline coding algorithm standardized by CCITT/ISO. The wavelet representation forms a pyramid in which information is layered in terms of different priorities, which facilitates more efficient use of forward error correction coding (FEC). After error sensitivity analysis for different layers over a mobile radio channel, an error-control scheme based on block-interleaving and Bose Chaudhuri-Hocquenghem (BCH) codes is proposed to minimize the effect of bursty channel errors on picture quality degradation. Application of the new technique to the proposed Telecommunications Industry Association (TIA) North American digital cellular standard (IS-54) under different vehicle speeds is also investigated
