  • Patent number: 8159985
    Abstract: A system and method of registering or exchanging information about the availability of multimedia information and services is disclosed. Access devices in a wireless local area network (WLAN) and/or personal area network (PAN) may register, with a wireless broadband access gateway, selected information about multimedia information and services that they have and may share. Information about the available multimedia information and services may be shared by the wireless broadband access gateway with other access devices within the coverage area of the WLAN or PAN. Access devices may then access the multimedia information and services of other access devices via the wireless broadband access gateway, based upon information identifying and authenticating the recipient. A broadband connection permits the gateway to pass multimedia information and service activity to and from the access devices within the coverage area of the WLAN or PAN.

  • Patent number: 8145982
    Abstract: Aspects of a method and system for redundancy-based decoding of voice content in a wireless local area network (WLAN) system are provided. A WLAN receiver may determine whether a decoded portion of a received packet comprises voice content and may select a redundancy-based decoder to decode a remaining portion of the packet when voice content is detected. The redundancy-based decoder may be a Viterbi decoder. The redundancy-based decoder may be selected to decode a determined number of subsequent packets or to decode subsequent packets for a determined amount of time. After decoding the remaining portion of the packet and any subsequent packets, the WLAN receiver may select a standard Viterbi decoder to decode additional received packets. The WLAN receiver may generate at least one signal to select the redundancy-based decoder and the standard Viterbi decoder.

  • Patent number: 8139695
    Abstract: Enhanced performance is achieved by combining channel coding with the space-time coding principles. With K synchronized terminal units transmitting on N antennas to a base station having M?K receive antennas, increased system capacity and improved performance are attained by using a concatenated coding scheme where the inner code is a space-time block code and the outer code is a conventional channel error correcting code. Information symbols are first encoded using a conventional channel code, and the resulting signals are encoded using a space-time block code. At the receiver, the inner space-time block code is used to suppress interference from the other co-channel terminals and soft decisions are made about the transmitted symbols. The channel decoding that follows makes the hard decisions about the transmitted symbols. Increased data rate is achieved by, effectively, splitting the incoming data rate into multiple channels, and each channel is transmitted over its own terminal.

  • Patent number: 8116823
    Abstract: The present invention provides a modular headset operable to support both voice communications and voice activated commands. This may involve the use of multiple voice CODECs to process voice communications and voice activated commands. The modular headset includes both a microphone and wireless earpiece. The earpiece may further include an interface, a processing circuit, a speaker, a user interface, a pairing circuit, and a registration circuit. The interface allows the earpiece to communicate with the base unit that couples the modular headset to a servicing network. This coupling to the servicing network and base unit only occurs when the headset is successfully registered to the base unit. The pairing circuit and registration circuit allow the exchange of pairing or registration information between various components. The pairing circuit allows the wireless earpiece and microphone to exchange pairing information which is then compared to determine whether or not a successful pairing can be achieved.

  • Patent number: 8111617
    Abstract: A system and method for utilizing multiple independent communication pathways for communication. Various aspects of the present invention may comprise receiving a first signal directly from a first communication network, where the first signal communicates a unit of information. A second signal may be received from a second communication network, where the second signal communicates the unit of information. The received first and second signals may be processed to determine the unit of information. For example, respective indications of reliability may be determined and utilized to select between the units of information determined from the first and second signals. Also for example, such indications of reliability may be utilized to calculate the unit of information (e.g., based on a weighted averaging technique).
