Space-time constellations for partial receiver CSI based on code combination
2005 (English)In: 2005 39th Asilomar Conference on Signals, Systems and Computers, NEW YORK: IEEE , 2005, 403-407 p.Conference paper (Refereed)
We consider the design of space-time constellations when the channel state information (CSI) that is available at the receiver is an estimate of the channel coefficients with known error covariance. This setup encompasses the well-studied scenarios of perfect and no channel knowledge and allows a smooth transition between these two cases. We design constellations adapted to the error covariance of the receiver CSI by a suitable combination of constellations proposed for perfectly known and unknown channel at the receiver. Simulations confirm the benefits of the presented design.
