摘要 Compressed sensing is famous for its compression performances over existing schemes in this field. Conventional researches aim at reaching the larger compression ratio at the encoder, with acceptable quality of reconstructed images at the decoder. This implies the error-free transmission between the encoder and the decoder. Unlike existing researches which look for compression performances, we apply compressed sensing to digital images for robust transmission in this paper. For transmitting compressed sensing signals over lossy channels, error propagation would be expected, and the ways to apply some means of protection for compressed sensing signals would be much required for guaranteed quality of reconstructed images. We propose to transmit compressed sensing signals over multiple independent channels for robust transmission. By introducing the correlations between the compressed sensing signals from different channels, induced errors from the lossy channels can be effectively alleviated. Simulation results have presented the reconstructed image qualities, which depict the effectiveness for the protection of compressed sensing signals.
