In this letter, we investigate the design of adaptive space-time codes that exploit partial transmitter channel state information (CSI). We introduce the adaptive space-time parsing paradigm as a generalization of the transmitter selection-diversity approach. We then use this new framework to construct full-diversity adaptive space-time codes for delay-limited applications with fixed-rate transmission. The proposed codes allow for reduced-complexity decoders and are robust to inaccuracies in the transmitter CSI.
