  • Patent number: 9048906
    Abstract: Beamforming precoding matrix using non-uniform angles quantization. Adaptively generated feedback information is provided between communication devices that communicate using more than one communication path, link, connection, etc. With respect to feeding back different types of information having different respective characteristics (e.g., different respective probability density functions), different and respective quantization may be employed for the different types of information. For example, uniform, Gaussian, or per bit loop optimized quantization may be individually selected and employed for each of the different types of feedback information used in a wired communication system (e.g.

  • Publication number: 20150146827
    Abstract: The present disclosure is directed to a system and method for detecting burst noise. The system and method are described in the exemplary context of a cable modem system and can be used in such a system to specifically detect upstream burst noise. Once detected, the system and method can adjust the upstream receiver that receives data corrupted by the upstream burst noise to reduce the potentially deleterious effects that the burst noise can have on, for example, the packet error rate and/or data rate of the upstream receiver.

  • Patent number: 9042368
    Abstract: Gateway based and centric network management and coordination. Coordination and management of delivery of a source sequence, that has possibly undergone adaptive bit rate (ABR) encoding upstream to generate a number of respective fragments that may have different respective bit rates associated therewith, to one or more downstream, user, or client devices is achieved via appropriate communication network management and coordination performed by one or more communication devices within the system. In one instance, a home gateway communication device operates to perform such coordination management of a convergent network or convergent digital home network (CDHN). Consideration of any one or more local and/or remote conditions, parameters, etc. may be employed by such an application to ensure effective delivery of a source sequence to one or more client devices.

  • Patent number: 9031143
    Abstract: A communication device is configured adaptively to process a receive signal based on noise that may have adversely affected the signal during transition via communication channel. The device may be configured to identify those portions of the signal of the signal that are noise-affected (e.g., noise-affected sub-carriers of an orthogonal frequency division multiplexing (OFDM) signal), or the device may receive information that identifies those portions of the signal that are noise-affected from one or more other devices. The device may be configured to perform the modulation processing of the received signal to generate log-likelihood ratios (LLRs) for use in decoding the signal. Those LLRs associated with noise-affected portions of the signal are handled differently than LLRs associated with portions of the signal that are not noise-affected. The LLRs may be scaled based on signal to noise ratio(s) (SNR(s)) associated with the signal (e.g., based on background noise, burst noise, etc.).

  • Patent number: 9021329
    Abstract: Impulse and/or burst noise signal to noise ratio (SNR) aware concatenated forward error correction (FEC). Adaptive processing is performed on a signal based on one or more effects which may deleteriously modify a signal. For example, based on a modification of a signal to noise ratio (SNR) associated with one or more impulse or burst noise events, which may be estimated, different respective processing may be performed selectively to differently affected bits associated with the signal. For example, two respective SNRs may be employed: a first SNR for one or more first bits, and a second SNR for one or more second bits. For example, as an impulse or burst noise event may affect different respective bits of a codeword differently, and adaptive processing may be made such that different respective bits of the codeword may be handled differently.

  • Publication number: 20150033314
    Abstract: Systems and methods for push button configuration of devices are provided. One system comprises one or more circuits configured to determine that a configuration button on the second device has been activated and determine whether a configuration button has been activated on a first device or a third device within a time interval from a time at which the button on the second device is activated.

The circuits are configured to, in response to determining that the configuration button has not been activated on either the first device or the third device within the time interval, prevent admission of the second device. The network may be a wired network, such as a MoCA network.

  • Patent number: 8942220
    Abstract: An example of a method of policing a flow in a home network such as a MoCA network may include calculating a policing period, calculating a first credit parameter, initializing a first usage variable at a beginning of the policing period, receiving a packet at an ingress node, calculating the first usage variable based on a first formula, determining whether the first usage variable is less than or equal to the first credit parameter, and making a reservation request when the first usage variable is less than or equal to the first credit parameter. The reservation request is different from an opportunistic reservation request. Examples of a system and a computer program product having instructions stored in a tangible computer-readable storage medium are also provided.

  • Patent number: 8863249
    Abstract: A first device coupled to a multimedia over coax alliance (MoCA) network may receive, from a second device, an indication that a configuration button on the second device has been pushed. The first device may receive, from a third device, an indication that a configuration button on the third device has been pushed. The first device may allow the second device to be authenticated on the MoCA network if the configuration buttons of the second and third devices were both pushed within a determined amount of time. The first device may prevent the second device from being authenticated on the MoCA network if the configuration button of the second device and the configuration button of the third device were not pushed within a determined amount of time. The indication from the third device may comprise a layer 2 management entity (L2ME) message or a Protocol Information element.

  • Patent number: 8811509
    Abstract: Forward error correction (FEC) m-bit symbol modulation.

  • Publication number: 20140201592
    Abstract: A communication device is configured to encode and/or decode low density parity check (LDPC) coded signals. Such LDPC coded signals are characterized by LDPC matrices having a particular form. An LDPC matrix may be partitioned into a left hand side matrix and the right hand side matrix. The right hand side matrix can be lower triangular such that all of the sub-matrices therein are all-zero-valued sub-matrices (e.g., all of the elements within an all-zero-valued sub-matrix have the value of “0”) except for those sub-matrices located on a main diagonal of the right hand side matrix and another diagonal that is adjacently located to the left of the main diagonal. A device may be configured to employ different LDPC codes having different LDPC matrices for different LDPC coded signals. The different LDPC matrices may be based generally on a common form (e.g., with a right hand side matrix as described above).

  • Publication number: 20140177741
    Abstract: A communication device is operative to generate and orthogonal frequency division multiplexing (OFDM) symbol that includes one or more data and ranging modulation symbols. The data and ranging modulation symbols may be included within different sub-carriers of the OFDM symbol. The OFDM symbol is used to generate an OFDM symbol pair in the frequency domain (FDOM). After conversion from the FDOM to the time domain (TDOM), the OFDM symbol pair may then undergoes post-processing in the TDOM before transmission. Such post-processing may include the addition of cyclic prefix (CP) and cyclic suffix (CS) to the OFDM symbol pair in the TDOM as well as filtering using a window function. The OFDM symbol may be generated as an orthogonal frequency division multiple access (OFDMA) symbol, and two were more OFDM symbols or OFDMA symbols may be arranged in a frame.
