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

  • obtaining a plurality of channel response matrices for a channel response of a MIMO channel in the MIMO system;

    computing a correlation matrix for the MIMO channel based on the plurality of channel response matrices; and

    decomposing the correlation matrix to obtain at least one steering vector for at least one spatial channel of the MIMO channel, wherein the at least one steering vector is used by a transmitting entity for frequency-independent spatial processing of a data stream sent on the at least one spatial channel associated with the at least one steering vector.
