Image coding for noisy channels
M. Reza Soleymani, S.D. Morgera, René Quesnel · 1991
The concept of vector trellis quantization is presented and applied to the encoding and decoding of still images for transmission over noiseless and noisy communication channels. A design procedure for a channel-optimized vector trellis quantizer is described. The criterion used in the design procedure is the expected squared error distortion measure. Simulation results using real images and a binary symmetric channel indicate that substantial signal-to-noise ratio improvement can be achieved at low, fractional transmission rates and high bit error rates.>
