摘要：
A novel compression scheme for video sequences that is robust to fading errors in a spread spectrum environment is presented. A 3D coder has been designed in which thr sequence was decomposed into spatio-temporal sub-bands and encoded using vector quantisation. Channel simulation shows good image reconstruction with a PSNR of 27dB under thr worst-case channel conditions of 18dB.
