Publication number: 20210056437Abstract: There is provided a method of selecting subpopulations of users mapped to subpopulations of entities, comprising: receiving latent factors of a mapping between users and entities and a predicted correlation value for each undefined mapping, computed by a recommender process, for each respective latent factor: identifying, by a user semantic model, user features of the users correlated to the respective latent factor, identifying, by an entity semantic model, entity features of the entities correlated to the respective latent factor, generate combinations of pairs each including one user feature and one entity feature, for each pair, compute statistical metric(s) indicative of a change relative to the predicted correlation value for the users and the entities, select pair(s) according to a requirement of the statistical metric(s), and provide the user feature and the entity feature for each selected pair.Type: ApplicationFiled: August 25, 2019Publication date: February 25, 2021Applicant: SparkBeyond Ltd.Inventors: Shiri Simon-Segal, Raz Alon, Guy Shaked, Meir Maor, Amir Ronen, Ron Karidi, Sagie Davidovich, Elad Shaked

Patent number: 10693695Abstract: A transmitter comprises a first peak-to-average-power ratio (PAPR) suppression circuit and a second peak-to-average-power ratio (PAPR) suppression circuit. The first PAPR suppression circuit may receive a first sequence of time-domain symbols to be transmitted, alter the first sequence based on each of a plurality of symbol ordering and/or inversion descriptors to generate a corresponding plurality of second sequences of time-domain symbols, measure a PAPR corresponding to each of the second sequences, select one of the plurality of symbol ordering and/or inversion descriptors based on the measurement of PAPR, and convey the selected one of the symbol ordering and/or inversion descriptors to the second PAPR suppression circuit. The second PAPR suppression circuit may receive the first sequence of time-domain symbols to be transmitted, and alter the first sequence based on the selected one of the symbol ordering and/or inversion descriptors to generate a reordered and/or inverted symbol sequence.Type: GrantFiled: February 14, 2018Date of Patent: June 23, 2020Assignee: MAXLINEAR, INC.Inventors: Curtis Ling, Tim Gallagher, Elad Shaked

Patent number: 10291267Abstract: Systems and methods are provided for band-limited digital pre-distortion (DPD) expansion estimation and curve adjustment. Pre-distortion adjustments may be applied during processing of an input signal, and expansion introduced as result of applying the pre-distortion adjustments may then be estimated. Expansion adjustments may then be determined based on the estimated expansion, and the expansion adjustments may be applied in a feedback manner during subsequent processing operations.Type: GrantFiled: August 4, 2016Date of Patent: May 14, 2019Assignee: MAXLINEAR, INC.Inventor: Elad Shaked
