Abstract
A technique for precoding a signal to be transmitted over a physical channel from a sender to a receiver is provided. A method includes receiving precoding information and applying precoding matrix at the sender based on the precoding information. The precoding information is received via a feedback mechanism from the receiver. The application of the precoding matrix results in a precoded signal for transmission over the physical channel. The precoding matrix enhances mutual information at the receiver.
