Abstract: A method receives data from entities indicative of whether or not an anomalous event is occurring at the entities over a first time period. The method characterizes the system, based on the data and a system characterization model, as one of: a system in which only the first entity is experiencing an anomalous event at any one time; a system in which two or more of the plurality of entities are experiencing anomalous events occurring at any one time; and a system for which during at least one second time period within the first time period data is missing for one or more of the plurality of entities. The method uses one or more anomaly detection models to compare the data received from the first entity to the data received from other entities in the plurality of entities, and determine that a local anomalous event has occurred at an entity.

Abstract: An electronic device may include wireless circuitry with a transmit antenna that transmits signals and a receive antenna that receives reflected signals. The wireless circuitry may detect a range between the device and an external object based on the transmitted signals and the reflected signals. When the range exceeds a first threshold, the wireless circuitry may use the transmitted signals and received signals to record background noise. When the range is less than a second threshold value, the wireless circuitry may detect the range based on the reflected signals and the recorded background noise. This may allow the range to be accurately measured within an ultra-short range domain even when the device is placed in different device cases, placed on different surfaces, etc.

Abstract: The present disclosure is directed to improvements in interference mitigation for Adjacent Channel Leakage in wireline communication, and more specifically, but not exclusively, to improved kernel designs that can facilitate interference mitigation for Adjacent Channel Leakage in cable modem systems. Examples of the present disclosure provide an apparatus for a transceiver device that comprises interference cancellation circuitry configured to cancel interference caused by upstream signals in one or more upstream sub-bands on one or more downstream sub-bands based on a combination of a plurality of kernels. The interference is at least partially caused by non-linearities within a transmission circuitry of the transceiver device, the plurality of kernels representing the non-linearities within the transmission circuitry of the transceiver device. Each of the kernels comprises one or more associated terms, with each of the associated terms being in-band for at least one of the one or more downstream sub-bands.

A discontinuity between a filtered past frame and a filtered current frame of the audio signal is removed using linear predictive filter. Removing the discontinuity further comprises processing a beginning portion of the filtered current frame, wherein the beginning portion of the current frame comprises a predefined number of samples being less or equal than a total number of samples in the current frame, and wherein processing the beginning portion of the current frame comprises subtracting a beginning portion of a zero-input-response (ZIR) from the beginning portion of the filtered current frame.

Abstract: Systems and methods comprising: receiving a signal (S) having a first interfering signal component (FISC); generating a replicated SOI (RSOI); and iteratively performing a process to obtain residual errors for FISC. The process involves: modifying an amplitude of RSOI; obtaining a reference signal (RS) by removing RSOI with the modified amplitude from S; analyzing frequency of RS to obtain an estimated carrier frequency and an estimated symbol rate for FISC; generating a remaining signal by removing, from FRS, a signal having the estimated carrier frequency and symbol rate; and determining a residual error of the remaining signal. Parameters for FISC are then set equal to the estimated carrier frequency and symbol rate that are associated with a lowest residual error. The parameters may be further refined in accordance with another process which involves iteratively modifying a symbol rate of FISC. Yet another process may be performed to determine filter parameters.
