1 Correction to: Signal, Image and Video Processing https://doi.org/10.1007/s11760-020-01715-2
Unfortunately, the above article has been published with some typos in it.
The corrected sentences are given below:
-
1.
In n the subsection 4.1 Derivation of the proposed algorithm (IPNLMS), under part (b) Step 2: Simplifcation, the second line in fourth paragraph should read as:
This replacement is to set a fxed overall adaptation step-size independent on the infuence of the input signal power \( \sigma_x^2 \), and to have an update equation form comparable to IPNLMS
-
2.
In equation (27), the zero symbol ‘0’ in \( {\mathbf{0}}_{N_{q}\times1} \)should be written in bold because it refers to the vector of the first Nq zero elements in m. In addition, the elements of the vector should be spaced and separated, as shown below:
$${\mathbf{m}}_{N\times1}=\left[\varvec{{0}}_{N_{q}\times1}, \quad 1, \quad e^{-1/\phi}, \quad e^{-2/\phi}, \ldots, e^{-(N_{m}-1)/\phi} \right] ^{\varvec{T}}$$(27) -
3.
In equation (28) the zero symbols ‘0’ should be written in bold because they refer to the zero portions in the matrix w. That is:
$$ {\mathbf{w}}=\left[\begin{array}{cc} {\mathbf{0}}_{N_{q}\times N_{q}} & {\mathbf{0}}_{N_{q} \times N_{m}} \\ {\mathbf{0}}_{N_{m}\times N_{q}} & {\mathbf{P}}_{N_{m}\times N_{m}} \\ \end{array}\right] {\mathbf{m}}+{\mathbf{q}}$$(28)
