A method for processing signals to be transmitted in a MIMO system from a transmitter having at least two transmitting antennas to a receiver having at least two receiving antennas on a frequency selective communication channel. The method comprises estimating elements of a channel matrix H(q−1) based on time delays and complex valued coefficients associated with the communication channel to provide an estimated frequency variation function of each element of the channel matrix, and pre-coding the signals to be transmitted based on the estimated frequency variation function for each element. The invention also relates to a MIMO system; and a transmitter and a receiver for use in a MIMO system.
A method for processing signals to be transmitted in a Multiple Input Multiple Output (MIMO) system from a transmitter having at least two transmitting antennas to a receiver having at least two receiving antennas on a frequency selective communication channel, comprising the steps of:
A Multiple Input Multiple Output (MIMO) system having a transmitter having at least two transmitting antennas and a receiver having at least two receiving antennas, the MIMO system being configured to process signals to be transmitted from the transmitter to the receiver on a frequency selective communication channel, the MIMO system comprising:
A transmitter configured to communicate with a receiver in a Multiple Input Multiple Output (MIMO) system on a frequency selective communication channel, the transmitter having at least two transmitting antennas and configured to process signals to be transmitted to the receiver, the transmitter comprising:
A receiver configured to communicate with a transmitter in a Multiple Input Multiple Output (MIMO) system on a frequency selective communication channel, the receiver having at least two receiving antennas, the receiver comprising an estimator configured to estimate elements in a channel matrix H(q−1) based on time delays and complex valued coefficients associated with the communication channel to provide an estimated frequency variation function of each element of the channel matrix H(q−1) and means to communicate the estimated frequency variation function to the transmitter.
