Abstract
A method for analog transmission of video from a transmitter using multiple transmit antennas includes transmitting analog video signals through at least two antennas to a receiver, monitoring at the receiver an attribute of the channels between the transmit antennas and an antenna of the receiver, and changing a phase and magnitude of an analog video signal being transmitted through at least one of the at least two antennas responsive to the monitoring. Additionally, a method for analog transmission of video signals using multiple transmit antennas includes space-time coding.
