Abstract
A system and method for transmitting signals via multi-input single-output (MISO) broadcast channel with imperfect channel state information at the transmitter (CSIT). The transmitter receives each CSI of from the plural receivers, determines a transmit power and a transmission rate based on the CSI qualities of the plural receivers calculated from the each CSI, and transmits the signal using the transmit power and the transmission rate. The signal comprises a user specific message, a first common message and a second common message to compensate imperfect CSIT.
