  • System and Method for Multiple Input, Multiple Output (MIMO) Communications
    Publication number: 20110126067
    Abstract: A system and method for MIMO communications is provided. A method includes receiving a data block of P matrices from a transmitter, and determining if operating conditions are met. The method also includes if operating conditions are not met, computing a test position, selecting a codeword based on the test position, and computing a metric. The metric may then be compared with an error radius to determine a validity of the codeword. If the codeword is invalid, another codeword is selected. If the codeword is valid, then the codeword is stored if all matrices have been evaluated, else another matrix is selected for evaluation. If matrices earlier in the data block have untested codewords while all codewords for a matrix being evaluated have been tested, backtracking may be performed. After the codewords for the data block have been found, the stored data may be outputted and processed.

  • Mobility route optimization in a network having distributed local mobility anchors
    Publication number: 20110080866
    Abstract: A method, system and device for achieving an optimized mobility routing path are disclosed. A preferred embodiment comprises a method of cutting unnecessary network tunnels. In a mobile network system, transmitting data packets through a tunnel is an effective way to provide network location privacy. An optimization method is proposed to consolidate two tunnels connecting with a network element such as a first distributed local mobility anchor (D-LMA). The first D-LMA informs a data packet sender such as a second D-LMA of the destination address saved in the first D-LMA. The second D-LMA updates its destination address accordingly and sends subsequent data packets to the destination directly. By applying this optimization method, a network system provides a further optimized route for data packets as well as location privacy.
