Abstract: A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architecture communicates content according to an initial bonding configuration. The communication architecture may adjust the bonding configuration to adapt to bonding environment changes affecting the communication capabilities or requirements associated with transmitting the content.

Abstract: Smart meter media access control (MAC) for single user, multiple user, multiple access, and/or MIMO wireless communications. Different types of wireless communication devices may be implemented within various wireless communication systems. Some of these devices may be implemented to communicate sensing and/or measurement to one or more other devices. For example, certain devices may be implemented to perform monitoring associated with any of a number of services provided by service providers (e.g., electricity, natural gas, water, Internet access, telephone service, and/or any other service). In accordance with such sensing and/or measurement related applications, a given device need not necessarily be awake or at a fully operative state at all times. Appropriate coordination, scheduling, communication medium access, etc. among potentially many implemented devices ensures effective communication and gathering of such sensing and/or measurement related data (e.g., using one or more service period (SP) announcements, various communication medium access options, etc.).

Abstract: A wireless communication device includes a communication interface and a processor that operate to generate a first transmission stream by processing first information based on first parameter(s) and a second transmission stream by processing second information based on second parameter(s). In some examples, the second at least one parameter is relatively less robust than the first at least one parameter, and the second information augments the first information when combined with the first information. The wireless communication device then transmits the first transmission stream and the second transmission stream to at least one other wireless communication device. Examples of such parameters include forward error correction (FEC) code, error correction code (ECC), modulation coding set (MCS), modulation type including a mapping of constellation points arranged in a constellation, power (e.g., transmit (TX) power), orthogonal frequency division multiplexing (OFDM) configuration, and/or a multiple-input-multiple-output (MIMO) configuration.

Abstract: A system and method supporting over-the-air programming of access device such as, for example, a mobile multimedia handset and a wireless personal digital assistant (PDA) via a broadband access gateway, is disclosed. The broadband access gateway may receive identifying information from the access device via a personal area network and/or a wireless local area network, and may transfer the identifying information to a wide area network or a third party content provider, via a broadband network. The broadband access gateway may enable the registration of the access device with the wide area network, and may receive firmware/software updates and/or provisioning parameters via the broadband network. The gateway may then transfer the firmware/software update and/or provisioning parameters to the access device via the personal area network and/or wireless local area network.

Abstract: A differential amplifier includes a positive leg, a negative leg, and biasing circuitry. The positive leg includes at least one positive leg transistor, a first positive leg degeneration capacitor, and positive leg degeneration capacitor biasing circuitry configured to bias the first degeneration capacitor during a reset period. The negative leg includes at least one negative leg transistor, a negative leg degeneration capacitor, and negative leg degeneration capacitor biasing circuitry configured to bias the negative leg degeneration capacitor during the reset period. The biasing circuitry biases current of both the at least one positive leg transistor and the at least one negative leg transistor based on capacitance of the first positive leg degeneration capacitor, capacitance of the first negative leg degeneration capacitor, and a sampling time during an amplification period. The differential amplifier may be a stage amplifier in an Analog to Digital Converter (ADC).

In some implementations, the first PHY includes a router and a PHY circuit. The router is configured to receive a plurality of data packets from a MAC device, to route one or more of the data packets having a first address to the PHY circuit, and to route one or more of the data packets having a second address to the second PHY chip.

Abstract: A device includes circuitry configured to determine characteristics of jammer signals associated with a first wireless protocol of another device. An amount of interference between the jammer signals and a first received signal at the device associated with a second wireless protocol is determined, and the jammer signals are filtered from the second received signal when the amount of interference between the jammer signals and the first received signal is greater than a first predetermined threshold.

Abstract: A wireless local area network (WLAN) transmitter includes a baseband processing module and a plurality of radio frequency (RF) transmitters. The processing module selects one of a plurality of modes of operation based on a mode selection signal. The processing module determines a number of transmit streams based on the mode selection signal. The processing of the data further continues by converting encoded data into streams of symbols in accordance with the number of transmit streams and the mode selection signal. A number of the plurality of RF transmitters are enabled based on the mode selection signal to convert a corresponding one of the streams of symbols into a corresponding RF signal such that a corresponding number of RF signals is produced.

Abstract: A system to implement a communication line coding scheme using a non-complex bit-to-symbol mapping, a forward error correction (FEC) coding, and an additive bit scrambler after the FEC at the PHY layer is provided. The system may be a part of or implemented by an automobile component. The system may be a PHY device configured to convert data from the MAC layer into 2D-PAM3 symbols that are transmitted across a communication link at a predetermined transmission rate, such as to be compliant with a communication standard. The PHY device may select characteristics of the conversion, such as the FEC coded symbol, based on the target transmission rate. The PHY device may include a transceiver, and may convert the data from MAC layer to PHY layer and back.
