Abstract
Techniques are provided for estimating an auto-correlation matrix for a transceiver that is coupled to a multi-antenna array. A different power sensor may measure the power of the signals received at a corresponding antenna of the multi-antenna array. The signals received at one antenna of each unique pair of antennas may be shifted in phase using a plurality (e.g., three) of different phase settings to generate a plurality of different shifted signals for each unique pair of antennas. Each of one or more power sensors, for each unique pair of antennas, may measure different combined powers based on the shifted signals and the RF signals received at the other antenna of the unique pair. A module may use the different combined powers with the power measured for each antenna to estimate the auto-correlation matrix.
