Abstract: Wide band adaptive beam forming methods and systems are provided. The beam forming methods can include receiving signals at multiple antenna elements and digitizing samples of the received signals for some period of time. The samples are divided into sub-channels according to frequency, and interferers are identified as signals appearing across at least some minimum number of the sub-channels. After removing signals not identified as interferers from the collected signal information, that information is used to calculate weights for forming a beam having a null at the identified location of the interferer. The beam forming systems include multiple element antennas having arms in the form of a spiral, and processing hardware for performing adaptive beam forming.

Abstract: A mobile communication device (e.g. a handheld telephone device) has a first wireless transceiver for communications via a wireless communication network and a second wireless transceiver for communications with a wireless peripheral device (e.g. a wireless audio headset or earpiece). The mobile device receives, from the wireless peripheral, an identification of a type or model of the wireless peripheral. The mobile device causes user interface (UI) function mapping information of the wireless peripheral to be selectively retrieved based on the received identification of the type or model. The UI function mapping information is indicative of a plurality of device functions assigned to a plurality of user input controls of the wireless peripheral. UI instruction information which is based on the retrieved UI function mapping information is then displayed at the mobile device.
