Abstract
A method, system and device are provided for using a predetermined vector, vref and channel knowledge H, G from each transmitter to compute and feedback equivalent channel vector information hi,jeq to its affiliated transmitter. With this information, each transmitter selects Li receivers and constructs a transmitted signal by applying a selected precoding vector to rank 1 data, thereby eliminating interference to the rest of the receivers in the network.
