Abstract

In "On the Bounds of Feedback Rates for Pilot-Assisted MIMO Systems," by Zhang et al, the authors calculated the bounds of feedback rates for pilot-assisted multiple-input-multiple-output (MIMO) systems. However, the nontrivial error of an equation in the Appendix has been found in the derivations, which led to inexact numerical results on the capacity with respect to the signal-to-noise ratio (SNR). We correct the error by recalculating the bounds of feedback rates.
