A Construction Algorithm of Measurement Matrix with Low Coherence for Compressed Sensing
In order to improve the accuracy and range for application of signal reconstruction, a new measurement matrix optimization method is proposed based on the Gram matrix. The new method can reduce the mutual coherence between the measurement matrix and the sparse transform matrix. Numerical experiments verify the success of the optimized method. Compared with the original Gaussian random matrix and other optimized measurement matrices, the performance and stability of our proposed have a slight increase.
