Abstract
A method, system and device are provided for using an indexed list of linearly independent, predetermined vectors V={v,. . . , v} and channel knowledge H, G from each transmitter to compute and feedback equivalent channel matrix information Hto its affiliated transmitter based on the assigned/determined rank of the receiver. With this information, each transmitter selects Lreceivers and constructs a transmitted signal by applying a selected precoding matrix to the mixed rank data, thereby eliminating interference to the rest of the receivers in the network.
