Cascade source coding with side information at first two nodes Conference Paper uri icon


  • We consider the cascade rate-distortion problem where side information is known to the source encoder and to the first user but not to the second user. We characterize the rate- distortion region for this problem. For the quadratic Gaussian case we show that it is enough to consider jointly Gaussian distributions; a fact that leads to an explicit solution.
