Abstract: Certain aspects of the present disclosure provide techniques for applying digital pre-distortion with frequency selectivity to a transmission signal. An example technique includes determining one or more target parameters of an input signal, the one or more target parameters being based on frequency of the input signal. The technique also includes applying digital pre-distortion with frequency selectivity to the input signal according to the one or more target parameters of the input signal to generate a resulting signal. The technique further includes processing the resulting signal to generate an analog signal for transmission and transmitting the analog signal.

Abstract: A coax network unit (CNU) is coupled to a coax line terminal (CLT). In first and second modes of operation, the CNU transmits data during an upstream window and receives data during a downstream window. In the first mode of operation, a duration of data transmission for the upstream window or a duration of data reception for the downstream window is reduced by a specified amount with respect to the second mode. A sounding signal is transmitted in the first mode in a probing slot that has a duration corresponding to the specified amount.

Abstract: An optical-coax unit (OCU) includes an optical PHY to receive and transmit optical signals and a coax PHY to receive and transmit coax signals. The OCU also includes a media-independent interface to provide a first continuous bitstream from the optical PHY to the coax PHY and a second continuous bitstream from the coax PHY to the optical PHY. The first continuous bitstream corresponds to received optical signals and transmitted coax signals, and the second continuous bitstream corresponds to received coax signals and transmitted optical signals.

Abstract: Methods, systems, and devices are described for generating a hybrid waveform for data transmission between a transmitting device and a receiving device. The transmitting device may employ an OFDM processing technique to periodically transmit known first pilot symbols mapped from a signal constellation where each signal has equal energy during a first time period and a cyclic prefix based single-carrier (CP-SC) processing technique to transmit data packets and second known pilot symbols during a second time period. Channel estimation is based on first pilot symbols, which are inserted into all subcarriers of OFDM symbol blocks within a specific period. Channel estimation tracking is based on the second pilot symbols interleaved within data packets. The receiving device may be configured to estimate CSI based in part on first pilot symbols and to track the channel estimation based in part on the second pilot symbols in order to provide reliable data detection.

Abstract: A network device includes a plurality of physical-media entities (PMEs), each corresponding to a distinct channel, to generate transmit signals based on transmit packets received over a media-independent interface. The network device also includes a channel-bonding sublayer to direct the transmit packets from the media-independent interface to respective PMEs of the plurality of PMEs. The channel-bonding sublayer has a substantially fixed delay between the media-independent interface and the plurality of PMEs for the transmit packets.

Abstract: A coax network unit (CNU) receives downstream bursts from a coax line terminal (CLT) and transmits upstream bursts to the CLT. The downstream bursts include start markers that indicate the beginnings of the downstream bursts and may also include pilot symbols. The downstream bursts are continuous across available resource elements in a matrix of subcarriers and orthogonal frequency-division multiplexing (OFDM) symbols. The available resource elements exclude resource elements in the matrix that carry the pilot symbols. The upstream bursts may include start markers indicating the beginnings of the upstream bursts and end markers indicating the ends of the upstream bursts. Respective upstream bursts are transmitted in respective groups of one or more resource blocks allocated to the CNU.
