Abstract:
|
In this paper we address the design of a multiple transmit antenna
system in which the Channel State Information (CSI) at the transmitter
is not perfect. Two different approaches are analyzed one
based on the Minimization of the Mean Square Error (MMSEj and
the other based on the application of the Maximum Likelihood Sequence
Estimation (MLSE). In both cases a Bayesian criterion is
used in order to take into account the error between the CSI and
the real channel. Finally, some simulation results and conclusions
are provided, showing which is the gain of these approaches when
the error between the CSI and the real channel is either Gaussian
or uniform, where this last case corresponds to a quantization of
the channel time response in order to transmit the CSI through a
feedback channel from the receiver to the transmitter. |
