    • A method and apparatus for channel determination for time division duplex systems with coupled antennas. A signal can be received at a receiving device (715). The signal can be based on a first product of an inverse of a transmit coupling matrix of a transmitting device and a receive coupling matrix of the transmitting device. A second product of a transmit coupling matrix of the receiving device and an inverse of a receive coupling matrix of the receiving device can be calculated (720). A receive channel from the transmitting device to the receiving device using reference symbols transmitted by the transmitting device can be measured at the receiving device (725). A reverse channel can be determined based on the signal and based on a third product of the second product and the transpose of the measurement of the receive channel (730). A precoded signal based on the reverse channel can be transmitted (750).
