1. A method of performing channel estimation in a wireless multiple-input multiple-output (MIMO) communication system, comprising:

  • receiving a steered pilot via at least one eigenmode of an uplink from a user terminal, the steered pilot being transmitted via a plurality of antennas at the user terminal;

    estimating a channel response of the at least one eigenmode of the uplink for the user terminal based on the received steered pilot;

    deriving a matched filter based on the estimated channel response of the at least one eigenmode of the uplink;

    receiving a data transmission via the at least one eigenmode of the uplink from the user terminal; and

    using the matched filter for matched filtering of the data transmission.
