Abstract
An important advantage of the fixed rate source coding scheme DCT and Product Pyramid VQ with (L-K)-thresholding is, besides its very good performance, the ability to calculate very precisely the expected mean square error caused by data compression mses. This together with the a-priori ability to calculate the bit-sensitivity of the compressed image data enables us to perform a highly efficientunequal error protection for image transmission over noisy channels. We show how to optimize the ratio of source to channel rate for transmission of compressed still images over a Gaussian channel (and a Rayleigh fading channel) using unequal error protection, and we present gains of up to 6 dB (7 dB) in PSNR compared to the image compression standard JPEG.
