摘要
Multiple Description Coding (MDC) is a new developed method to overcome fading in wireless communications. It enhances the robustness of information transmission over non-prioritized and unpredictable networks. A novel MDC framework for images based on the Space-Frequency Quantization (SFQ) algorithm is proposed in this paper. The redundancy is introduced through the improved zerotree quantization and the simple odd-even estimation method. In comparison with other schemes, the simulation results show the efficiency of the proposed method.
