Comments and Corrections to “Capacity of Multiple-Antenna Systems With
Both Receiver and Transmitter Channel State Information”
Abstract
In this correspondence, we correct the ergodic capacity versus SNR
curves of the coherent multiple-input
multiple-output (MIMO) channel in independent and identically
distributed (IID) Rayleigh fading in the correspondence cited in the
title. More importantly, the corrected capacity results present an
interesting and compelling contrast between performances of the coherent
MIMO systems with and without channel state information at the
transmitter; whereas this view is somewhat limited in in the
correspondence cited in the title because of flaws in the capacity
curves.
