Correction to: Communications Engineering https://doi.org/10.1038/s44172-024-00333-x, published online 18 February 2025

In the version of the article initially published, in the numerator of Eq. (4) “CSBRx” should have read “CSBTx”. In the numerator of Eq. (5), “CSBTx” should have read “CSBRx”. In the HTML and PDF versions of the article, the equations have now been corrected to:

$${C}_{1}=\frac{{C}_{{{\rm{SBTx}}}}{C}_{{{\rm{SG}}}}}{{C}_{{{\rm{SBRx}}}}+{C}_{{{\rm{SG}}}}+{C}_{{{\rm{SBTx}}}}}$$
(4)

and

$${C}_{2}=\frac{{C}_{{{\rm{SBRx}}}}{C}_{{{\rm{SG}}}}}{{C}_{{{\rm{SBRx}}}}+{C}_{{{\rm{SG}}}}+{C}_{{{\rm{SBTx}}}}}$$
(5)
