  • Method and apparatus in relaying system
    Patent number: 8526355
    Abstract: An apparatus, comprising a channel estimator for estimating channel coefficients of communication channels of multiple-input-multiple-output communication, a precoder for applying the estimated channel coefficients to precode a transmit signal to cancel the impact of the communication channels on the transmit signal, a first controller for providing the transmit signal for multiple-input-multiple-output transmission in a first timeslot, a second controller for processing a multiple-input-multiple-output receive signal received in a second timeslot following the first timeslot, and a cancellator for cancelling the transmit signal from the receive signal.
