摘要： A physical layer transceiver for connecting a host device to a wireline channel medium includes a host interface for coupling to the host device, a line interface for coupling to the channel medium, a transmit path operatively coupled to the host interface and the line interface, a receive path operatively coupled to the line interface and the host interface, and adaptive filter circuitry operatively coupled to at least one of the transmit path and the receive path for filtering signals on the at least one of the transmit path and the receive path, the adaptive filter circuitry including a non-linear equalizer. The non-linear equalizer may be a neural network equalizer based on a multi-layer perceptron or a radial- basis function, or may be a linear equalizer with a non- linear activation function. The non-linear equalizer also may have a front-end filter to reduce input complexity.

摘要： A receiver (500) for use in a data channel on an integrated circuit device includes a non-linear equalizer (501) having as inputs digitized samples (521) of signals on the data channel, decision circuitry (501) configured to determine from outputs of the non-linear equalizer a respective value of each of the signals, and adaptation circuitry (573) configured to adapt parameters of the non-linear equalizer based on respective ones of the value. The non-linear equalizer may be a neural network equalizer (541), such as a multi-layer perceptron neural network equalizer, or a reduced complexity multi- layer perceptron neural network equalizer. A method for detecting data on a data channel on an integrated circuit device includes performing non-linear equalization of digitized samples of input signals on the data channel, determining from output signals of the non-linear equalization a respective value of each of the output signals, and adapting parameters of the non-linear equalization based on respective ones of the value.

摘要： A physical layer transceiver, for connecting a host device to a wireline channel medium having a cable length, includes a host interface for coupling to a host device, a line interface for coupling to the channel medium, and filter circuitry operatively coupled to the line interface. The filter circuitry includes a plurality of filter segments, fewer in number than a total number of link segments in the cable length. Individual filter segments in the plurality of filter segments are configurable to correspond to individual link segments and are separately controllable from other filter segments. Control circuitry detects a change of transmission conditions in a particular link segment, and upon detection of the change of transmission conditions, changes a configuration of one of the plurality of filter segments to cause an alteration in filtering of signals in the particular link segment at which the change of transmission conditions is detected.

摘要： A printed circuit board (PCB) includes a substrate defining a major plane. A first side of the major plane is configured for mounting of functional circuit elements. A cable connector is mounted on a second side of the major plane of the substrate, opposite the first side, for coupling to a shielded radiofrequency (RF) communications cable. At least one component grounding layer is parallel to the major plane and configured for coupling to the functional elements. At least one cable grounding layer is parallel to the major plane and is separated from the at least one component grounding layer. Each cable grounding layer in the at least one cable grounding layer is coextensive with the substrate and is configured for coupling, through the connector, to shielding of the shielded RF communications cable, without coupling to any other component. Nodes of an RF communications system may be mounted on such PCBs.

摘要： Systems and methods are provided for securely sharing data. A processor forms two or more shares of a data set encrypted with a symmetric key, the data set associated with a first user device, and causes the encrypted data set shares to be stored separately from each other in at least one remote storage location. The processor generates first and second encrypted keys by encrypting data indicative of the symmetric key with a first asymmetric key of first and second asymmetric key pairs associated with the first user device and a second user device, respectively, and causes the encrypted key to be stored in the at least one storage location. To restore the data set, a predetermined number of the two or more encrypted data set shares and at least one of the second asymmetric keys of the first and second asymmetric key pairs are needed.
