A method and apparatus is described for modifying a smart antenna processing strategy determined from a set of signals received at an array of antenna elements of a wireless station, such as a set of weights for processing received antenna signals or forming a set of antenna signals for transmission. The method and apparatus uses the signatures of one or more interferers to produce a modified processing strategy that improves the nulling to the one or more interferers in that, when the modified strategy is applied on the downlink, the transmit signal strength in the direction of the one or more interferers is decreased, and, when the modified strategy is applied on the uplink, the sensitivity to signals from the direction of the one or more interferers is decreased.

Null deepening for an adaptive antenna based communication station

A power sharing apparatus and method. In one embodiment, a method of sharing power includes switchably coupling and decoupling each of a plurality of power sources to deliver at least a portion of power to a shared power supply. Each of the power sources corresponds to one of a plurality of applications. The method also includes adjusting the portion of power delivered by each one of the power sources to the shared power supply responsive to an amount of usage by the application corresponding to the respective power source.

Method and apparatus for sharing power

A birdcage coil is operated in a balanced mode through connection of signal ground to a shield surrounding the coil. The driven leg of the coil includes tune capacitors, through which balance is maintained.

Shielded drive for balanced quadrature bird cage coil

Angular and current distributions for an elliptical birdcage resonator are realized in a design that achieves constant electrical phase between adjacent legs of the coil. Equal peak currents in the driven legs of the orthogonal modes yields exact quadrature operation.
