Multiple-antenna concepts
for wireless communication systems promise high spectral efficiency and low
error rates by proper exploitation of the randomness in multipath propagation,
without increase in the transmit power or bandwidth. The subject of this work
is to quantify the impact of channel uncertainty due to channel estimation
errors on the error-rate performance and the capacity of multiple-antenna
systems in Rayleigh and Ricean block-fading (BF)
channels. A training-based system is considered that reserves a portion of time
to sound the channel. The transmitter sends known pilot symbols that are used
to estimate the channel at the receiver by means of a linear filter. No CSI is
assumed at the transmitter.
A new framework to analyze
training-based multiple-antenna systems is introduced. The core piece of this
framework is an equivalent system model that specifies the channel by the
estimated (and hence, known) channel coefficients and an uncorrelated,
data-dependent, non-Gaussian noise. We derive the maximum-likelihood (ML)
detector and investigate its performance in the limit of perfect CSI and no CSI
as well as its relation to several mismatched detectors.
New exact expressions and Chernoff bounds of the
pairwise error probability are derived and applied to assess word-error and
bit-error rate bounds for ML and mismatched detection. Upper and lower bounds
on the maximum instantaneous mutual information and the maximum mutual
information are presented and used to compute ergodic and outage capacities and
to extend earlier results to arbitrary (and possibly mismatched) linear channel
estimators and to correlated Ricean BF channels. For
illustration purposes, several numerical results are included, ranging from
simple single-antenna systems to multiple-antenna schemes in correlated Ricean fading and orthogonal frequency-division
multiplexing (OFDM) systems over frequency-selective fading channels with
robust channel estimation.
