Abstract
Common transmit processing concepts are either based on complete, partial, or no channel state information (CSI). But the quality of CSI is crucial for a fair comparison. Therefore, we derive an explicit expression of the bit error probability (binary modulation) for the transmit matched filter, beamforming, and Alamouti space-time block code in case of linear estimation and prediction of the channel coefficients or a delay of the channel estimates. Uncorrelated as well as correlated frequency flat channels are considered. Based on the analytical expressions a comparison for these three representatives for all three types of CSI is made. The break even point between the three schemes is computed numerically, which can serve as a switching point between the concepts.
