Abstract: Systems and methods are provided for communication ultra-high definition (UHD) video. At the transmitter-side, a single packet stream that includes packets corresponding to a plurality of encoded content streams may be generated, and the single packet stream may be split into a plurality of sub-streams. The splitting may include grouping packets corresponding to the single packet stream into a plurality of chunks, each associated with a respective one of the sub-streams; adding handling related information to each of the chunks; and incorporating into at least one packet in a first one of the sub-streams at least some of handling related information associated with a second one of the sub-steams. The sub-streams may then be processed for transmission over a particular physical medium. At the receiver-side, the signals may be received and processed, and the sub-streams may be reconstructed based on processing of the plurality signals.

Abstract: A wireless communication device (WCD) establishes an ad-hoc communication link with a second WCD within operating range. A replica of at least a portion of a display of the first WCD may be shared with the second WCD utilizing wireless broadband signals that are communicated via the established one or more ad-hoc communication links. The first WCD and the second WCD are operable to communicate the wireless broadband signals at a power level that is below a spurious emissions mask. The transmitted wireless broadband signals are spread so they occupy a designated frequency spectrum band. The shared replica of at least a portion of the display of the first WCD includes one or more applications, text, video and/or data content. A user of the first WCD may interact with content that is displayed on a display of the second WCD and vice-versa.

Abstract: In an example implementation of this disclosure, a message passing low density parity check (LDPC) decoder may, during decoding of a first group of bits, lock a first variable node upon a bit-value probability of the first variable node reaching a determined threshold, and lock a first check node upon all variable nodes connected to the first check node being locked. The LDPC decoder may cease decoding the first group of bits upon all variable nodes of the LDPC decoder being locked, all check nodes of the LDPC decoder being locked, reaching a maximum number of iterations, or reaching a timeout. During a particular iteration of the decoding of the first group of bits in which the first variable node is locked, the LDPC decoder may refrain from generating a bit-value probability for the locked first variable node.

Abstract: Methods and systems for time interleaved analog-to-digital converter timing mismatch calibration and compensation may include receiving an analog signal on a chip, converting the analog signal to a digital signal utilizing a time interleaved analog-to-digital-converter (ADC), and reducing a blocker signal that is generated by timing offsets in the time interleaved ADC by estimating complex coupling coefficients between a desired digital output signal and the blocker signal utilizing a decorrelation algorithm on frequencies within a desired frequency bandwidth. The decorrelation algorithm may comprise a symmetric adaptive decorrelation algorithm. The received analog signal may be generated by a calibration tone generator on the chip. An aliased signal may be summed with an output signal from a multiplier. The complex coupling coefficients may be determined utilizing the decorrelation algorithm on the summed signals. A multiplier may be configured to cancel the blocker signal utilizing the determined complex coupling coefficients.

Abstract: Methods and systems for providing reduced bandwidth acquisition latency may comprise communicating a reservation request for bandwidth allocation for devices operating under a wired network protocol, where the reservation request may be sent by wired network devices via a wireless network protocol over a wireless network. Bandwidth may be allocated in the wired network for the requesting devices by a network controller. Data may be communicated with the requesting devices via the wired network. The wired network communication protocol may comprise a multimedia over cable alliance (MoCA) standard. The wireless protocol may comprise an IEEE 802.11x standard, a Bluetooth standard, and/or any non-public network protocol. The communication of the reservation request via the wireless protocol may decrease a latency of the wired network. A medium access plan (MAP) may be generated by the network controller based on the reservation request and may comprise a bandwidth allocation for the requesting devices.
