Blind Deconvolution Using Modulated Inputs.

This paper considers the blind deconvolution of multiple modulated signals/filters, and an arbitrary filter/signal. Multiple inputs s1, s2, ... ,sN =: [sn] are modulated (pointwise multiplied) with random sign sequences r1, r2, ... ,rN =: [rn], respectively, and the resultant inputs (sn ⊙ rn) ∈ ℂQ, n ∈ [N] are convolved against an arbitrary input h ∈ ℂM to yield the measurements yn = (sn ⊙ rn) ⊕ h...
