Paper Abstract

Distributed compressed sensing theory is applied to many practical problems, ECG signal, color imaging, etc. In order to improve the reconstruction accuracy of multi-dimensional signals, this paper applies singular value decomposition to the multi-measure vector problem in DCS, then distributed compressed sensing reconstruction method based on singular value decomposition is proposed. This method can achieve row orthogonality of the measurement matrix and does not affect the design of the reconstruction matrix. Numerical experiments verify the effectiveness of the proposed method, which can significantly improve the reconstruction quality of the signal and the robustness to noise.
