Abstract: A communication device includes a communication interface and a processor configured to generate, transmit, receive, and process signals. The communication device generates orthogonal frequency division multiplexing (OFDM) frame(s) that include a two-dimensional (2D) start burst marker (BM), a data payload, and a 2D stop BM, and transmits the OFDM frame(s) to another communication device. Alternatively, the communication device receives OFDM frame(s) that include a 2D start BM and a 2D stop BM, and then identifies a data payload within those OFDM frame(s) based on the 2D start burst marker and a 2D stop BM. The 2D start and stop BMs are based on predetermined sequences having particular formats based on corresponding 2D sub-carrier and OFDM/A frame based structure. A receiver communication device then detects the 2D start BM and 2D stop BM within the received OFDM frame(s) based on knowledge of these predetermined sequences and particular formats.

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.

Abstract: The problem with duty-cycle correction circuits used by conventional frequency doublers is that they typically analog solutions, such as variable delay lines with long chains of inverters or buffers, that directly adjust the reference signal used by a phase-locked loop (PLL). These solutions can considerably increase the noise (e.g., thermal noise and supply noise) of the reference signal, as well as the overall power consumption and cost of the PLL. Rather than directly correct the duty-cycle of the reference signal, the present disclosure is directed to an apparatus and method for measuring the period error between adjacent cycles of a frequency doubled reference signal in terms of cycles of the output signal generated by the PLL (or some other higher frequency signal) and adjusting the division factor of the PLL frequency divider to compensate for the measured period error.

Abstract: Systems and methods for transmitting packets over a network of communication channels are provide. A system according to the invention may include first and second nodes in communication with a coax backbone. The first node may further include a retransmission buffer. The system may also include a network access coordinator operative to coordinate access of the nodes to the coax backbone. In a time period at least one first packet is transmitted by the first node to the second node. The first packet may include an indication that retransmission service is applied. The first packet may also include a indication of the length corresponding to the packet. If, during the first time period the packet is not received by the second node, the second node is operative to send a retransmission request to the network access coordinator.

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, apparatus and computer program product are provided to allow the idle period to be defined in a more tailored manner, such as on a per station or per class of stations basis, as opposed to on a per access point basis. In the context of a method, an indication of an idle period is caused to be provided to a station. The method also causes an association with the station to be maintained for a period of time that is at least partially defined by the idle period. The period of time for which an association is maintained with the station is different than a period of time for which an association is maintained with another station in an absence of communication with the another station. A corresponding apparatus and computer program product are also provided.

Abstract: A field effect transistor (FET) having one or more fins provides an extended current path as compared to conventional finFETs. A source terminal is disposed on a first fin between a first dummy gate and a gate structure. A drain terminal is disposed on a second fin between a second dummy gate and a third dummy gate. A first gate oxide layer disposed under second and third dummy gates is made to be thinner than a second gate oxide layer disposed under the first dummy gate and the gate structure. By making the first gate oxide layer thinner, an overall footprint of the finFET device is reduced.

Abstract: An electronic device is operable to determine a Global Positioning System (GPS) mode of operation based upon accelerometer input. The electronic device includes a communications interface, a GPS receiver, an accelerometer module, and processing circuitry. The processing circuitry receives an accelerometer output from the accelerometer module and compares the accelerometer output to a plurality of acceleration signatures. Based upon the comparison, an acceleration profile is selected. A GPS mode of operation is selected for the GPS receiver based upon the acceleration profile. The acceleration profile can be selected based upon one or more types of communications being serviced by the communications interface. In one embodiment, a selected GPS mode of operation selected corresponds to a distinct operating environment.

Abstract: A cable network gateway receives a downstream broadband signal via service provider cabling at an interface. An Analog to Digital Converter (ADC) converts the downstream broadband signal to a digital downstream broadband signal. A digital filter attenuates an upper spectrum from the digital downstream broadband signal to produce a filtered digitized downstream broadband signal. An in-home communications transceiver produces a digital in-home communications signal that overlaps the upper spectrum. Summing circuitry sums the filtered digitized downstream broadband signal with the digital in-home communications signal to produce a combined digital signal. A Digital to Analog Converter (DAC) converts the combined digital signal to a combined analog signal and an in-home cable interface transmits the combined analog signal via in-home cabling. The downstream broadband signal may be a Data over Cable System Interface Specification (DOCSIS) 3.0/3.

Abstract: Embodiments provide systems and methods for enabling a wireless multi-access communication system having a first frequency band and a second frequency band. The first frequency band can be used to establish a first channel using a non-Massive Multiple Input Multiple Output (M-MIMO) radio access technology (RAT). The first channel can be used to broadcast downlink/uplink control information (and, optionally, data) between an access point (AP) and a user device. The second frequency band can be used to establish a second channel using a M-MIMO RAT. The second channel can be used to communicate high speed downlink/uplink data between an AP and a user device. The non-M-MIMO RAT and the M-MIMO RAT can be of the same RAT family or of different RAT families.
