Abstract
This paper presented a DCT-based image coder optimized for transmission over binary symmetric channels. The proposed coder uses a robust channel-optimized trellis-coded quantization stage that is designed to optimize the image coding based on the channel characteristics. This optimization is performed only at the level of the source encoder, and does not include any channel coding for error protection. The robust nature of the coder increases the security level of the encoded bit stream and provides a much more visually pleasing rendition of the decoded image. Consequently, the proposed robust channel-optimized image coder is especially suitable for wireless transmission due to its reduced completely, its robustness to non-stationary signal and channels, and its increased security level.
