  • Patent number: 8706070
    Abstract: An RF system for reducing intermodulation (IM) products is disclosed. The RF system includes a first nonlinear element and a second nonlinear element, wherein the second nonlinear element generates inherent IM products and the first nonlinear element is adapted to generate compensating IM products. Alternatively, the first nonlinear element generates inherent IM products and the second nonlinear element is adapted to generate compensating IM products. The amplitudes of the compensating IM products are substantially equal to amplitudes of the inherent IM products. The RF system further includes a phase shifter that is adapted to provide a phase shift that results in around 180° of phase shift between the inherent IM products and the compensating IM products. The phase shifter is coupled between the first nonlinear element and the second nonlinear element.

  • Patent number: 8706041
    Abstract: A wireless communication system and constituent wireless communication devices are provided to implement a distributed, cognitive radio approach to spectrum sharing. Under the distributed approach, individual wireless communication devices self-enforce negotiated agreements on usage of an available spectrum without intervention from a centralized authority. Particularly, individual wireless communication devices are configured to enhance information rates of their respective transmissions under predetermined constraints. The predetermined constraints can include transmit power constraints (e.g., a maximum power available to the wireless communication devices), or interference constraints (e.g., constraints on the amount, direction, and/or quality of interference generated by transmissions).

  • Patent number: 8688062
    Abstract: A communications system includes spaced apart sensing nodes each configured to receive signals within occupied portions of a frequency spectrum, and a coordinator node configured to communicate with the spaced apart sensing nodes. The coordinator node determines the occupied portions of the frequency spectrum, and determines unoccupied portions of the frequency spectrum based upon the occupied portions. A pair of wireless communications devices is configured to communicate with each other and with the coordinator node. The pair of wireless communications devices may operate within an unoccupied portion of the frequency spectrum based on using a communications signal comprising a continuous phase modulated waveform, with at least one waveform parameter being selected to reduce interference with the occupied portions of the frequency spectrum.

  • Patent number: 8655353
    Abstract: Disclosed is an enhanced system and method for bridging calls across telecommunications networks, including an illustrative application of the invention as it relates to international roaming among prepaid wireless subscribers. For instance, whenever wireless subscribers roam internationally they may invoke the system by keying in an Unstructured Supplementary Service Data (USSD) short code followed by the number to be dialed. Said subscriber's prepaid account is then decremented in real-time (until such account is fully depleted). A key feature of the disclosure generally is the bridging of the call legs between the wireless subscriber initiating the telephone communication and that of the receiving party through a series of general purpose databases and computers without requiring modifications to existing core network or handset infrastructure.

  • Patent number: 8639189
    Abstract: When a device in one wireless network receives interfering transmissions from an overlapping neighboring network, the neighboring network may be notified of the interference so that non-interfering schedules can be worked out. In one embodiment, the device receiving the interference may broadcast its own communications schedule. Device(s) in the interfering network may pick up that schedule, and pass it on to their controller, which can rearrange its own network schedule to be non-interfering. In another embodiment, the device receiving the interference may notify its own network controller with the pertinent information, and that controller may contact the controller of the interfering network to coordinate non-interfering schedules.
