摘要： Systems, methods, and devices are described for generating multi-tone waveforms. A count signal having a count value is generated. A plurality of step values and a plurality of phase values are received. For each increment of the count value, an index value corresponding to each step value of the plurality of step values is calculated based on the step value, the count value, and a respective phase value of the plurality of phase values. A tone point value corresponding to each calculated index value is determined to generate a plurality of tone point values for each increment of the count value. The determined tone point values are summed to generate a corresponding waveform point for each increment of the count value. A waveform is generated as a sequence of generated waveform points.

摘要： Wireless signal processing may be improved by using a configurable baseband filter (BBF) in the receive path of a transceiver. A configurable BBF may accommodate processing of different wireless signals in a single integrated circuit (IC) chip. For example, a single IC may support processing of 5G mmWave RF signals and 5G sub-7 GHz RF signals by reconfiguring the BBF with settings appropriate for the different wireless signals. The reconfiguring of the BBF may include adjusting a bandwidth of the BBF and/or adjusting a filter order of the BBF. The reconfiguring of the BBF may be performed in response to detection of jammer signals to improve rejection of the jammer signals.

摘要： A method performed by a network node for detecting bandlimited interference in a single-carrier Uplink (UL) from a User Equipment (UE) in a wireless communications network is provided. The network node receives (201) a data sequence of the single-carrier UL. The network node defines (202) a kernel-based statistical two-sample test, forming a squared Maximum Mean Discrepancy, MMD, distance-measure. The network node obtains (203) a first sequence Y. The first sequence Y comprises a sequence of an integer of N samples comprising ideal UL data of a given configuration associated to characteristics of the single-carrier UL. The network node further obtains (204) a second sequence X, which second sequence X comprises a sequence of the integer of N samples from the received data sequence. The network node decides (206) whether or not bandlimited interference is present in the single-carrier UL, based on comparing (205) the first sequence Y with the second sequence X according to the defined kernel-based statistical two-sample test.

摘要： Embodiments described herein relate to methods and apparatuses for determining whether an anomalous event occurring at first entity within a system has occurred locally at the first entity. The system comprises a plurality of entities comprising the first 5 entity. A method comprises: receiving data from the plurality of entities indicative of whether or not an anomalous event is occurring at each of the plurality of entities over a first time period; characterizing the system, based on the received 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 0 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; and utilizing one or more of a plurality of 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 responsive to an 5 output of any of the one or more of the plurality of anomaly detection models indicating that the anomalous event has occurred locally at the first entity: determining that a local anomalous event has occurred at the first entity; and assigning a confidence level to the determination that the local anomalous event has occurred at the first entity, wherein the confidence level is based on the characterization of the system.
