The method of this embodiment may also include determining an uplink state flag value based on the plurality of weighted error measures.

Abstract: Embodiments of an apparatus and method for selective single-carrier (SC) equalization are provided. Multipath propagation in a communication channel often changes, and the severity of multipath propagation is often below worst case conditions supported by a SC communication device. When multipath propagation is less severe and below worst conditions, the use of frequency-domain equalization (FDE) in a SC receiver to mitigate ISI can be overkill and can result in excess power being consumed. The excess power consumption can be attributed to the general inability of the structure used to perform FDE to scale in terms of performance with channel conditions. Embodiments of the apparatus and method for performing selective equalization in a SC receiver allow either FDE or time-domain equalization (TDE) to be performed based on the current multipath propagation conditions of a communication channel. In general, TDE is used in place of FDE to conserve power when channel conditions permit.

Abstract: A STB, communicatively coupled to a server, receives a web page request when, for example, a URI, is entered into a web browser running in the STB. In response, the STB sends a processing assistance request to the server for processing the entire web page regardless of processing capability of the STB. The STB receives processed information resources or contents associated with the entire web page from the server. The server retrieves information resources or contents associated with the entire web page from a web server based on the received processing assistance request. The server determines content type such as video and/or graphics of the retrieved information resources or contents for corresponding content processing. The server determines content formats supported by the STB for content encoding. The STB decodes the resulting encoded information resources or contents from the server to render the entire web page in the STB.

Abstract: A system for multicast switching for distributed devices may include an ingress node including an ingress memory and an egress node including an egress memory, where the ingress node is communicatively coupled to the egress node. The ingress node may be operable to receive a portion of a multicast frame over an ingress port, bypass the ingress memory and provide the portion to the egress node when the portion satisfies an ingress criteria, otherwise receive and store the entire frame in the ingress memory before providing the frame to the egress node. The egress node may be operable to receive the portion from the ingress node, bypass the egress memory for the portion and provide the portion to the first egress port when an egress criteria is satisfied, otherwise receive and store the entire multicast frame in the egress memory before providing the multicast frame to an egress port.

Abstract: Methods, systems, and computer program products are provided to divide code blocks, such as blocks of quantized coefficient of image or video data, into smaller blocks and sub-blocks that can be processed in parallel using layered entropy coding and decoding scheme.

Abstract: A field effect transistor (FET) having one or more fins provides an extended current path as compared to conventional finFETs. A raised source terminal is disposed on a fin adjacent to a sidewall spacer of a gate structure. The drain terminal and a first portion of the gate structure overlie a first well of a first conductivity type. A raised drain terminal is disposed such that it is spaced apart from the gate structure sidewalls. In some embodiments the drain terminal is disposed on a second, separate fin. the drain terminal and a second portion of the gate structure overlie a second well of a second conductivity type.

Abstract: Embodiments recognize that in MIMO and M-MIMO systems, physical antennas tend to be closely spaced to each other (e.g., a grid). As a result, a spatial correlation typically exists between physical antennas as well as between transmissions from logical antenna ports. Embodiments exploit this characteristic to reduce the amount of pilot signaling needed to enable downlink channel estimation. Specifically, embodiments limit pilot signaling to only a subset of supported logical antenna ports and rely on spatial correlation information to interpolate channels from logic antenna ports for which no pilot signaling is used.

Link partners can be configured to exchange advanced NGBASE-T configuration information such as type, profile, capability and mode information of the PHY in one or more next page messages.

Abstract: Embodiments of a method and system for supporting co-existence of first and second cellular networks in adjacent channels in the same geographical area are provided. The method and system synchronize the two cellular networks such that their respective uplink transmissions are aligned in time and their respective downlink transmissions are aligned in time. Such synchronization prevents (or substantially prevents) the uplink transmissions from one of the two cellular networks from overlapping with the downlink transmissions of the other cellular network, and vice versa, thereby mitigating interference between the two networks.

Abstract: A mobile device may be operable to receive historical location trail information of a building. A location of the mobile device within the building may be determined by placing, moving or snapping a reference location of the mobile device onto a trail according to the received historical location trail information. The historical location trail information may be acquired from a location server. The historical location trail information stored in the location server may be generated using a plurality of location samples that are provided by one or more other mobile devices that have been within the building. The historical location trail information may also be acquired from an indoor map of the building that is used by the mobile device for navigation within the building. The determined location of the mobile device may then be utilized by the mobile device to navigate within the building for location-based services.

Abstract: Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications. In accordance with wireless communications, a signal (SIG) field employed within such packets is distributed or partitioned into at least two separate signal fields (e.g., SIG A and SIG B) that are located in different portions of the packet. A first of the SIG fields includes information that may be processed and decoded by all wireless communication devices, and a second of the SIG fields includes information that is specific to one or more particular wireless communication devices (e.g., a specific wireless communication device or a specific subset of the wireless communication devices). The precise locations of the at least first and second SIG fields within a packet may be varied, including placing a second of the SIG fields (e.g., including user-specific information) adjacent to and preceding a data field in the packet.

Abstract: A method and apparatus is disclosed to compensate for impairments within a data converter such that its output is a more accurate representation of its input. The data converter includes a main data converter, a reference data converter, and a correction module. The main data converter may be characterized as having the impairments. As a result, the output of the main data converter is not the most accurate representation of its input. The reference data converter is designed such that the impairments are not present. The correction module estimates the impairments present within the main data converter using its output and the reference data converter to generate corrections coefficients. The correction module adjusts the output of the main data converter using the corrections coefficients to improve the performance of the data converter.

Abstract: A system and method is provided for creating and detecting prefix-based entropy labels in a multi-protocol label switching communication network. Each label in a label stack is provided with at least a common prefix field and a computed hash field without the use of entropy label indicators (ELIs). Label stacks generated are processed by transit LSRs in an MPLS communications network where the transit LSR uses the first N labels of the label stack to determine the hash computations for load balancing. By scattering prefix-based entropy labels throughout the label stack, the transit LSR uses one or more prefix-based entropy labels for the hash computation.
