  • Methods and Systems for Adaptive Communication
    Publication number: 20110116573
    Abstract: One embodiment of the present invention relates to a method of transferring data in a communication system. In the method, an initial impulse noise protection value is determined. A number of redundancy bits is added to blocks of data to form codewords as a function of the initial impulse noise protection value, where the impulse noise protection value corresponds to a number of consecutive symbols that can be corrected. The number of symbols that can be correctly transmitted is changed by changing only the number of redundancy bits added to each block of data.

  • Multi-carrier communication via sub-carrier groups
    Patent number: 7894483
    Abstract: One embodiment of the present invention relates to a method for communicating over a multi-carrier communication channel. In the method, sub-carrier frequencies that are reserved for communication between a pair of network nodes are associated with different sub-carrier groups, where the sub-carriers of each sub-carrier group are assigned to a bitloading or gain configuration that is independent of the bitloading or gain configurations for the other respective sub-carrier groups. A group message, which is indicative of the bitloading or gain configurations for the respective sub-carrier groups, is transmitted from the receiving node to the transmitting node.

  • NETWORK RETRANSMISSION PROTOCOLS USING A PROXY NODE
    Publication number: 20100246414
    Abstract: One embodiment relates to a method for communicating over a transmission medium shared between a plurality of nodes including a source node, a proxy node, and other nodes. In the method, a transmission data unit is transmitted from the source node to the proxy node and to the other nodes. A confirmation is selectively transmitted from the proxy node to the other nodes based on whether a reception data unit corresponding to the transmission data unit is correctly received at the proxy node. Based on whether the confirmation is received at one of the other nodes, a negative acknowledgement is selectively transmitted from the one of the other nodes to the source node. Other methods and devices are also disclosed.

  • Transient robust channel for communication systems
    Patent number: 7769052
    Abstract: One embodiment of the present invention relates to a network device. The network device includes a receiver configured to be coupled to a transmission medium supporting a multi-carrier channel over which data is communicated as symbols in a first communication state according to an initial bit-loading configuration. The receiver is further configured to detect noise that can corrupt the symbols on the multi-carrier channel. In addition, the receiver is configured to, in response to the detected noise, allocate at least part of the multi-carrier channel to a transient robust channel that facilitates adaptive communication. Other methods and devices are also disclosed.

  • Methods and systems for determining communication parameters
    Patent number: 7738543
    Abstract: One embodiment of the present invention relates to a method of determining an impulse noise protection parameter in a communication system. In the method, it is determined if a first set of received data elements are corrupted so as to exceed an initial corruption threshold.

  • Updating and Distributing Encryption Keys
    Publication number: 20100042841
    Abstract: System and method for providing secure communications is provided. Initially, an exchange protocol, such as a password-authenticated key exchange protocol, is used to create a shared secret. From the shared secret, two keys are created: a utilized key and a stored key. The utilized key is used to encrypt messages between nodes. When it is time to replace the utilized key to maintain security, the stored key is utilized to encrypt messages for generating/distributing a new shared secret. The new shared secret is then used to generate a new utilized key and a new stored key. This process may be repeated any number of times to maintain security.
