  • Patent number: 11316600
    Abstract: Systems and methods for classifying interference in data signals received by a terminal device (or other end-user or endpoint device) transacting data in a data transfer network are disclosed. Embodiments include defining an array of signal quality metrics at the terminal device, where each signal quality metric is associated with a subcarrier of a data channel used to transfer data with the data transfer network. The array of signal quality metrics may be input to a classification model and the classification model may output a type, sources, and/or cause of disruptions such as interference identified in the signal quality data. In some cases, the output may include frequency characteristics such as a center frequency and/or bandwidth of the identified signal disruption. The terminal device may transmit a message to an upstream device of the data transfer network, which may indicate the identified interference.

  • Publication number: 20200097775
    Abstract: The present disclosure generally relates to apparatus, software and methods for detecting and classifying anomalous features in one-dimensional data. The apparatus, software and methods disclosed herein use a YOLO-type algorithm on one-dimensional data. For example, the data can be any one-dimensional data or time series, such as but not limited to be power over time data, signal to noise ratio (SNR) over time data, modulation error ratio (MER) data, full band capture data, radio frequency data, temperature data, stock data, or production data. Each type of data may be susceptible to repeating phenomena that produce recognizable anomalous features. In some embodiments, the features can be characterized or labeled as known phenomena and used to train a machine learning model via supervised learning to recognize those features in a new data series.

  • Publication number: 20190305876
    Abstract: A profile optimizing method is provided for a downstream channel transmission of active subcarriers to user devices. The method includes steps of receiving channel measurement data from each user device for each subcarrier, calculating a maximum bit-loading value for each user device per subcarrier, grouping the user devices into a plurality of clusters based on a proximity of the maximum bit-loading values of a first user device to those of a second user device within the particular cluster, assigning each user device within the particular cluster to a single cluster profile. A plurality of single cluster profiles for the plurality of clusters forms a set of cluster profiles. The method further includes steps of determining a channel capacity ratio for the set of cluster profiles, and combining at least two single profiles of the set of cluster profiles into a coalesced profile pair.
