摘要： A physical layer transmitter that communicates between nodes in a broadband cable network by transmitting and receiving packets containing data and control information. Packets are constructed by the physical layer transmitter and transmitted to one or more receiving nodes that are capable of processing the packets. Packets are directed to specific nodes utilizing link layer control data. The packets may also contain control information that may include formatting, encoding and modulation parameters that are capable of being processed by the appropriate receiving nodes. The physical layer transmitter allows node-to-node communication within a broadband cable network and each node in the network is capable of communicating with every other node in the network.

摘要： In a communication network, a sending node transmits a message with a multi-segment preamble and data to a receiving node. The receiving node calculates characteristics of the sending unit, channel, or transmitted signal by processing preamble segments. Once an unknown characteristic is determined, a segment of the preamble can be eliminated or reduced in length for subsequent messages, which increases efficiency of the message transmissions.

摘要： A local area network uses coaxial cable wiring for interconnection of terminal devices. A frequency selective network interface device is placed at the building point of entry or another point in the wiring to reflect network signals transmitted by terminal devices back into the building distribution to be received by other terminal devices. By reflecting network upstream signals back into the building as downstream signals, the network interface provides a path for terminal devices to transmit to and receive from other terminal devices.

摘要： A broadband digital communication network transmits a signal with a shaped power spectrum to minimize interference with devices that share the communication medium. In one embodiment using coaxial wiring, devices such as cable converters and televisions that are not part of the network share the communication medium and are exposed to the network signal. Power levels across the network band are selected to reduce interference in the non-networked devices. One area of susceptibility is the tuner of cable channel receivers, which perform mixing and down conversion of RF signals. The power spectrum profile is selected to minimize the IF and base band interference after down conversion. The spectrum can be shaped within each 6 MHz band to further minimize the interference with a TV signal. The power levels can be optimized for both peak power limitation and quantization effects.

摘要： A clock smoothing circuit generates a smoothed clock signal from a gapped clock signal having unevenly spaced pulses separated by gaps that result from the removal of data bits and from a reference clock signal having evenly spaced pulses that create a predetermined reference frequency. A smoothing element is coupled to the input elements to receive the gapped clock signal and the reference clock signal. In one embodiment, the smoothing element generates a smoothed clock signal having one pulse for each of the pulses in the gapped clock signal and having a frequency that is greater than one-half of the predetermined reference frequency. Each pulse in the smoothed clock signal is synchronized with a pulse in the reference clock signal. In another embodiment, the smoothing element includes an accumulator that counts the pulses of the reference clock signal, a modulo signal that resets the accumulator to a particular reset value when a predetermined number of pulses M is reached, and an output element that produces one pulse of the smoothed clock signal for each pulse of the reference clock signal on which the modulo element does not reset the accumulator.
