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: Successive pairs of OFDM symbols are transmitted by an OFDM transmitter and received by an OFDM receiver. The successive pairs include a first pair of OFDM symbols. First and second OFDM symbols of the first pair both include pilot symbols on two subcarriers that are symmetric about a center carrier frequency. The two subcarriers are the same for the first and second OFDM symbols. The pilot symbols on the two subcarriers for the first and second OFDM symbols compose an orthogonal matrix. The OFDM receiver estimates frequency responses at frequencies including the frequencies of the two subcarriers and compensates for signal impairment based at least in part on the estimated frequency responses.

Abstract: A receiver receives a repeating or periodic signal and, based on the signal, estimates a carrier frequency offset for the receiver. Based on the signal and the estimated carrier offset, an I/Q mismatch for the receiver is estimated and compensation for the estimated I/Q mismatch is performed. After compensating for the estimated receiver I/Q mismatch, the carrier frequency offset is re-estimated.

Abstract: A coax network unit (CNU) coupled to a coax line terminal (CLT) receives a plurality of orthogonal frequency-division multiplexing (OFDM) symbols from the CLT and identifies a start-of-frame delimiter on a physical-layer (PHY) control channel in the plurality of OFDM symbols. The PHY control channel includes a plurality of contiguous subcarriers. The CNU decodes one or more forward error correction (FEC) code words that follow the start-of-frame delimiter on the PHY control channel. The one or more FEC code words provide PHY control data that include information specifying a structure of a PHY frame that includes the plurality of OFDM symbols.

Abstract: A coax network unit (CNU) receives a first plurality of orthogonal frequency-division multiplexing (OFDM) symbols from a coax line terminal (CLT). The first plurality of OFDM symbols includes continual pilot symbols on one or more subcarriers. The CNU also receives a grant from the CLT allocating a set of subcarriers within a second plurality of OFDM symbols to the CNU. The CNU transmits upstream to the CLT using the allocated set of subcarriers within the second plurality of OFDM symbols. When transmitting, the CNU places non-continual pilot symbols on regularly spaced subcarriers of the allocated set of subcarriers and does not place continual pilot symbols within the allocated set of subcarriers.
Abstract translation: 同轴网络单元（CNU）从同轴线路终端（CLT）接收第一多个正交频分复用（OFDM）符号。 第一多个OFDM符号包括一个或多个子载波上的连续导频符号。 CNU还从CLT接收向第二多个OFDM符号内的一组子载波分配给CNU的授权。 CNU使用在第二多个OFDM符号内的所分配的一组子载波向CLT发送上行信号。 在发送时，CNU将非连续导频符号放置在所分配的子载波集合的规则间隔的子载波上，并且不将连续导频符号放置在所分配的子载波集合内。

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 method of registering a coax network unit (CNU) in a network is performed at an optical-coax unit (OCU). In the method, a first discovery message is broadcasted to a plurality of CNUs. In response, a first registration request is received from a first CNU of the plurality of CNUs. In response to the first registration request, a proxy entity corresponding to the first CNU is implemented in the OCU. A second discovery message is received from an optical line terminal (OLT). In response to the second discovery message, a second registration request is transmitted to the OLT requesting registration of the proxy entity with the OLT.
