WebMar 29, 2024 · The signal is sampled using a random matrix Ψ: y = Ψ x. where Ψ is a random matrix (measurement matrix). The discrete signal x [ n] = Φ s, i.e. it has a sparse representation under the specific basis Φ. Technically, there are multiple bases under which the signal is potentially sparse. The above equation becomes. y = Ψ Φ s. WebWe will say that the matrix obeys the strong incoherence property with parameter if one can take and both less than or equal to (this property is related to, but slightly dif-ferent from, the incoherence property, which will be discussed in Section I-F1).

WebThe concept of incoherence arose in compressed sensing. It is introduced in the context of matrix completion to ensure the singular vectors of are not too "sparse" in the sense that all coordinates of each singular vector are of comparable magnitude instead of just a few coordinates having significantly larger magnitudes.
