Abstract

In network coding, the successive original video frame data can be transmitted at once. However, if insufficient number of innovative packets are transmitted due to the packet loss or delay, network coding system is to be underdetermined. Thus, since network coding matrix (random coefficient matrix) is not invertible, original data cannot be recovered by matrix inversion. To solve this problem, in this paper, a new compressive sensing method with graph Laplacian regularizer is proposed, which exploits correlation between successive original video frame data. Experimental results demonstrate the effectiveness of proposed algorithm, implemented by the alternative direction multiplier method (ADMM) and show that PSNR values from reconstructed images are above 33dB with coding matrix Φ C^M×N of which measurement M = 0.75N and 22dB with measurement M = 0.66N, respectively.
