[0034] S1, the original signal Evenly divided into L segments, the length of each segment of the signal is equal and is an integer greater than 1, using a complete base Ψ makes the signal sparse in Ψ, each segment of the signal can be expanded in the same complete base, each segment of the signal Corresponding to different expansion coefficients , where Ψ is an orthogonal square matrix composed of characteristic basis vectors, L>1, and L is a natural number, a complete basis is a special matrix, and the column vectors of the matrix are linearly independent, and any signal can be It is represented by the linear sum of the column vectors in this matrix and the corresponding expansion coefficients. The eigenbasis vector refers to the eigenvector obtained after the eigenvalue decomposition of the matrix. These vectors are linearly independent and can be used to form a complete basis. Among them, Expand the coefficient range, which is a real number in [0.1,0], and the coefficien...
