摘要： The present disclosure provides radio-frequency (RF) systems that can detect the presence of RF signals received by the system, as well as determine characteristics such as the operating frequency of RF signals, the type of RF source that transmitted each RF signal, and/or the location of each RF source with high precision and sensitivity while using low cost, scalable electronics that are versatile enough for deployment in a variety of environments. Such systems can employ a network of RF sensors that can coordinate in response to communication with a computer to perform any such detection and/or determination using trained models executed onboard the RF sensors and/or the computer. RF signals may have unique characteristics when received at one or more RF sensors that may be detected using trained models described herein, even in high noise or non-line of sight (LOS) environments and with low cost, low resolution RF receiver hardware.

摘要： A system includes a vehicle event recorder and a modem. The vehicle event recorder is configured to receive a sensor data signal from a sensor that is mounted on a vehicle trailer. The modem is configured to demodulate the sensor data signal to create a modulated sensor data signal. The demodulated sensor data signal is received using a first line. The first line is coupled via a harness to sensor on a vehicle trailer.

摘要： Methods and apparatus for enhancing performance of a wireline communication network backhaul for a wireless node. In one embodiment, the node comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the methods and apparatus enable enhanced communication between the small cell/base station and the backhaul network so as to support adaptation by the wireline network for frequencies used by the node so as to mitigate interference or other issues. In one implementation, enhanced cable modem (CM), cable modem termination system (CMTS) and node devices coordinate to inform the CMTS of use of potentially interfering frequencies by the base station so that the CMTS can monitor, and reconfigure as necessary, any affected wireline RF channels.

摘要： A system and method for recovering encoded data from a modulated baseband signal is disclosed. Aspects and embodiments of the system and method include receiving an analog input signal representing a modulated baseband signal, counting clock cycles of a reference clock, detecting a first transition and a second transition of the analog input signal indicating a first change and a second change in the modulated baseband signal, storing a first counter value corresponding to an amount of clock cycles elapsed between the first transition and the second transition, and determining a binary-valued bit sequence corresponding to the first counter value.

摘要： A method for tuning an analog front end response is provided. The method includes determining a peaking control value for an analog front end (AFE) of a receiver, determining an attribute corresponding to the peaking control value, selecting the peaking control value as the operating peaking control value for the AFE based on the attribute being determined to be higher than a previous attribute, and performing a receiver adaptation using the peaking control for a one or more transmitter configurations.

摘要： An apparatus for identifying a communications signal in a preceding stage for a communications modem includes a communications signal identifying unit configured to receive a communications signal through a port, deliver data included in the communications signal to a communications modem, and sample the communications signal which has passed through the port during every unit length to detect a unit length pattern corresponding to a start of communication and a unit length pattern corresponding to an end of communication. When a length from the start of communication to the end of communication is equal to or smaller than a reference length, the communications signal identifying unit delivers a data process stopping signal to the communications modem such that the communications modem stops a data reading operation.

摘要： A wireless communication device includes one or more transmitter (TX)-receiver (RX) pairs, one or more RX distortion estimators, and a combiner. A first RX distortion estimator receives a first TX signal corresponding to a first TX of the first TX-RX pair and a second TX signal corresponding to a second TX of a second TX-RX pair. The first RX distortion estimator processes the first TX signal and the second TX signal based on a first base function set including at least one base function to generate a first distortion signal set including at least one distortion signal. Then, the first RX distortion estimator processes the first distortion signal set to generate a first RX correction signal. The wireless communication device's combiner generates a first distortion compensated RX signal by compensating for distortion in a first RX signal of the first TX-RX pair based on the first RX correction signal.
