Abstract

A method and apparatus for modifying functions in a wireless communication device are described herein. The wireless communication device may receive a selection that indicates a power or a signal processing functionality. The wireless communication device may then modify functions associated with a plurality of smart antennas based on the power or signal processing functionality and in relation to a reference design. The wireless communication device may then determine performance associated with the modified functions. The modified functions may, for example, include adjusting power of the smart antenna of the transmitter or receiver associated with the wireless communication device, adjusting power of the radio frequency (RF) chain of the transmitter or receiver associated with the wireless communication device, varying the number of antenna elements for transmissions or receptions, selecting a signal processing technique, or varying the power control algorithm.
