Systems and methods for performing precoding in multi-user systems

摘要

Systems and methods are provided for precoding a signal at a transmitter. A plurality of receiver devices is identified, and a first receiver device is selected from the plurality of receiver devices. The transmitter communicates with the first receiver device over a channel, and an estimate of the channel is determined. A precoding matrix is computed based on the estimate, such that when the transmitter transmits a signal that is precoded with the precoding matrix over the channel, interference from a second receiver device of the plurality of receiver devices over the channel is reduced.
