  • Estimation of downlink transmission parameters in a radio communications system with an adaptive antenna array
    Patent number: 6738020
    Abstract: A method and apparatus are provided that allows system calibration to be incorporated into a single function that also derives transmit parameters from receive parameters in a spatial diversity system. In one embodiment, the invention includes receiving signals at an antenna array from a plurality of different locations, deriving characterizations of the spatial parameters of the received signals, receiving measurements of a plurality of different signals transmitted from the antenna array to a plurality of different locations, deriving characterizations of the spatial parameters of the transmitted signals from the received measurements, and generating a transformation function for producing transmit spatial parameters based on measurements of received signals using the receive spatial parameter characterizations and the transmit spatial parameter characterizations.
