The Eq. (5) in Ref. [1] should be $$Y_1(\omega )=\frac{1}{2\pi }\sum _{n=0}^{N-1}{A}_n\exp (j{\varphi }_n)S^{*}({\omega }_c+n\mathrm{\Delta }{\omega }_c-\omega ).$$(5)

The position of the parentheses in the original manuscript is incorrect. This is a clerical error, and all of the theories and conclusions are unchanged by this correction.

The authors apologize for this error and any inconvenience to readers.
