20130266305 | OPTICAL-LAYER MULTIPATH PROTECTION FOR OPTICAL NETWORK - A multi-path provisioning scheme is provided to ensure full protection while reducing or minimizing resource overbuild. A signal to be provisioned is divided at a source node into a plurality of sub-signals that are independently routed from the source node to a destination node. Bandwidth for back-up traffic B is allocated in addition to bandwidth for primary traffic T. In some embodiments, the initial bandwidth B of the backup traffic equals the bandwidth of the primary traffic. The T+B traffic is initially distributed so that no link carries more than B traffic. The traffic distribution pattern is then iteratively revised to reduce the bandwidth requirements for the backup traffic while still meeting requirements for protection. | 10-10-2013 |

The wavelength switch network routes any wavelength channel that does not support a matching pair of client-side and edge-side ports to port discovery equipment at the hub node. The port discovery equipment searches for new ports, and, responsive to finding a new port, automatically discovers a predefined set of one or more attributes of the new port. The controller determines that a client-side port and an edge-side port are a matching pair of ports if discovered sets of attributes of those ports match according to one or more predefined rules. The controller then controls the wavelength switch network to re-route the wavelength channel supporting that matching pair between those ports. | 07-03-2014 |

20110058486 | Measuring Noise Power at Wireless Receivers Using Pilot Symbol Information - Embodiments are directed to a wireless receiver system that utilizes a special structure of pilot symbols used for synchronization and channel estimation in transmission packets to measure noise power at the receiver. The periodicity of the pilot signal sequences is used to extract the noise power from the received signal. Such extraction is achieved by subtracting the received signals from two pilot slots which are separated by the known periodicity of the training sequence. This method relies on the fact that desired signal and system interference signals will cancel out after the subtraction process. Measuring the power of the residual signal after subtraction represents the estimate of the noise power. Several consecutive such residual signals can be first summed up before measuring the power to improve the estimate of the noise power at the receiver. To further improve the performance, estimates of the desired signal produced by a channel estimation block can be first subtracted from each of the received signals on two pilot slots which are then to be subtracted and are separated by the known periodicity of the pilot sequence. | 03-10-2011 |

20130258873 | Adaptive Transmit Beamforming for Frequency Division Duplexing Systems - Embodiments of a method and apparatus for performing an adaptive transmission scheme in a frequency division duplexing communication system based on channel state information estimated using an open-loop mode are described herein. In one example, the method includes estimating an impulse response of a channel using a signal received over a first frequency band of the channel from a device, transforming the impulse response into a frequency response of the channel, and subsequently performing the adaptive transmission scheme using the frequency response to transmit a signal to the device over a second frequency band of the channel that is different from the first frequency band. | 10-03-2013 |
20140155117 | Shaping Table Reconfiguration At Communication Event Boundaries - A communication device, such as a smart phone, receives a power specification message from a network controller. The power specification message specifies an output power applicable for a particular communication subframe or symbol within the subframe. In response to the power specification message, the communication device determines a new shaping table and replaces an existing shaping table with the new shaping table. The communication device uses the shaping table to generate an envelope signal for an envelope tracking power supply, and the new shaping table is adapted to provide power saving operation at the specified output power. | 06-05-2014 |
20140155128 | Unequal Amplifier Gain Compression Via Shaping Table - A communication device, such as a smart phone, includes an envelope tracking power supply that provides a voltage supply signal for a power amplifier. The envelope tracking signal input to the envelope tracking power supply arises from application of a shaping table on a desired transmit signal. The shaping table implements non-uniform gain compression across a range of output powers, and in particular may aggressively compress the power amplifier for low output powers, and less aggressively compress the power amplifier at high output powers. The non-uniform gain implemented via the shaping table may provide significant power savings, while still allowing the transmitter to meet spectral mask requirements. | 06-05-2014 |

20130347113 | DETERMINING POPULATED IP ADDRESSES - A service log of a service provider is analyzed to identify IP addresses used by account holders that are populated IP addresses. Existing information about legitimate and malicious accounts of the service provider is leveraged to determine likely good and bad populated IP addresses based on the accounts that use the populated IP addresses. Features of the good and bad populated IP addresses are used to train a classifier that can identify good and bad populated IP addresses based on features of the populated IP addresses. The classifier may be used to provide security services to the same service provider or different service providers. The services include identifying malicious accounts. | 12-26-2013 |
