Correction: Quantization-aware sampling set selection for bandlimited graph signals

The Original Article was published on 29 January 2022

Correction to: EURASIP Journal on Advances in Signal Processing (2022) 2022:5

After publication of this article [1], the authors reported some errors in formulas in Sect. 4.1 and Table 1, as follows:

- In the first paragraph of Sect. 4.1, the formula

\(C_{GM} \,=\, (N-i)(2r^2+r+2i^2+3)\)

should have read:

\(C_{GM}\approx (N-i)(2ri+2i^2)\)

and \(C_{i+1}\approx 2Nr^2+2Ni^2-6r^2i\)

should have read \(C_{i+1}\approx 2Nri-4r^2i\)

and \(O(|S|^2(N|S|-r^2))\)

should have read \(O(Nr|S|^2)\)

- In Table 1, third column (operation count) \(O(|S|^2(N|S|-r^2))\)

should have read \(O(Nr|S|^2)\)

and \(O(|S|^2(N|S|-r^2))\)

should have read \(O(Nr|S|^2)\)

The author would like to apologize for any inconvenience caused.

The original article [1] has been corrected.
