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.
WebDec 8, 2024 · While working on an exercise, I stumbled upon the term mutual incoherence of a matrix. Upon googling, I didn't find much information outside of some of its properties, but nowhere any definitions. The only thing I found is the definition of a mutual coherence of a matrix. linear-algebra; Share. WebJan 11, 2024 · Incoherence expresses to what extent two different basis are orthogonal one to the other. A good measure of incoherence is provided by the scalar product: the lower the values, the higher the two basis are orthogonal.
