Causal/Predictive Imperfect Channel State Information in Block-Fading Channels

We consider a multi-input multi-output (MIMO) block-fadin g channel with a general model for channel state information at the transmitter (CSIT). Th e model covers systems with causal CSIT, where only CSIT of past fading blocks is available, and predictive CSIT, where CSIT of some future fading blocks is available. The optimal diversi ty-multiplexing… CONTINUE READING
