| Abstract: | A new blind sparsity iterative greedy reconstruction algorithm is presented based on studying the signal reconstruction algorithm for compressed sensing without the prior information of signal sparsity.A stage-wised and backtracking method is employed to adaptively adjust the candidate list at each iteration in order to estimate the true supporting set of the approximated signal.The theoretical analysis and experiment simulation prove that the performance of the algorithm outperforms that of the existing st... |
