Abstract
A method includes the step of interleaving training and feedback stages in a transmitter and a multiplicity of antennas, wherein the transmitter trains the corresponding ones of the multiplicity of antennas one by one and receives feedback information after training each one of the corresponding ones of the multiplicity of antennas. An apparatus operating using the method includes a multiple-input single-output system with t transmitter antennas, a short-term power constraint P, and target data rate ρ where for any t, the same outage probability as a system with perfect transmitter and receiver channel state information is achieved with a feedback rate of Rbits per channel state and via training Rtransmitter antennas on average, where Rand Rare independent of t, and depend only on ρ and P.
