New sensing matrices based on Modified Gram Schmidt of the Chebyshev chaotic matrix

The sensing matrix plays an important role in compressed sensing (CS) and a suitable choice of measurements will lead to a good sparse recovery performance.In this paper, we introduce Modified Gram Schmidt (MGS) of the Chebyshev chaotic matrix and Chebyshev circulant matrix, which have better performance than RandomGaussian, Chebyshev chaotic and Chebyshev circulant matrix.
