摘要：
In this paper, we consider a two description coding scheme based on a general frame synthesis operator. Through some approximations of the original rate-distortion problem, the design of the efficiently encoded coefficients is formulated as a convex optimization problem. We also show that there exists a close link between the proposed coding strategy and compressed sensing problems. Simulations results are provided to show the validity of our approach.
