  • Patent number: 8358713
    Abstract: In digital communication systems forward error correction coding techniques are typically used to improve the bit error rate performance. The receiver of the digital communication systems employs a decoding apparatus which may use Maximum A posteriori Probability (MAP) algorithm and its variations such as Logarithmic-MAP (Log-MAP), Maximum-Logarithmic-MAP (Max-Log-MAP). MAP decoding apparatus is commonly used as a key component in of decoder for error correcting codes such as convolutional codes and turbo codes. The MAP decoding apparatus computes likelihood estimates as the output. The present invention performs faster MAP decoding by computing likelihood estimates in parallel.

  • Patent number: 8260231
    Abstract: The present invention provides architectures and methods which use multiple radio receive chains in mobile devices to boost performance of the mobile devices. While a first set of the receive chains are assigned to a serving base station, another set of receive chains are dynamically allocated to neighbor base stations and/or to the serving base station depending upon present or expected system conditions and timing. A first synthesizer is configured to provide signals to the first and second set of receive chains. Other synthesizers are also configured to provide signals to the second set of receive chains. Thus, depending on the mode of operation, the second set of receive chains utilizes signals from a given synthesizer as needed. A priori data may be used to allocate specific receive chains to the serving base station, neighboring base stations or both. Unused synthesizers may be turned off to conserve power.

  • Patent number: 7305511
    Abstract: In one embodiment, a system for providing both wireline and wireless connections to a wireline interface includes a first wireline interface, a second wireline interface, a wireless interface, and a switch coupled to the first wireline interface, the second wireline interface, and the wireless interface. The switch can selectively couple the first wireline interface to the second wireline interface to allow communication between the first and second wireline interfaces. The switch can further selectively couple the first wireline interface to the wireless interface to allow communication between the first wireline interface and the wireless interface.

  • Patent number: 7127541
    Abstract: In one embodiment, a system for automatically establishing a wireless connection between adapters includes a master adapter coupleable to a peripheral device. The master adapter can automatically enter an inquiry mode in response to the occurrence of a first event. In the inquiry mode, the master adapter automatically establishes one or more wireless connections between the master adapter and one or more slave adapters that are coupled to one or more computer systems. The master adapter can also automatically enter an operational mode in response to the occurrence of a second event. In the operational mode, the master adapter enables communication between the peripheral device and the one or more computer systems via the one or more wireless connections using a wireless protocol.
