Turbo-code is a newly developed channel coding technique with amazing error correcting capability. It has attracted lots of attention in recent years, In this paper, turbo-codes are applied to JPEG compressed images in a wireless environment. Different combinations of source and channel code rates are simulated for image transmission. In addition, unequal error protection for the header syntax of JPEG compressed images is considered. It is found that turbo-codes combined with unequal error protection give excellent performance for compressed image transmission, even at very low channel signal-to-noise ratio. The optimum joint source/channel coding schemes are given at different signal-to-noise ratios. The image qualities are compared both subjectively and objectively
