Patent number: 9768914Abstract: A method for performing blind channel estimation for an MLSE receiver in a communication channel, according to which Initial Metrics Determination Procedure (IMDP) is performed using joint channel and data estimation in a decision directed mode. This is done by generating a bank of initial metrics that assures convergence, based on initial coarse histograms estimation, representing the channel and selecting a first metrics set M from the predefined bank. Then an iterative decoding procedure is activated during which, a plurality of decision-directed adaptation learning loops are carried out to perform an iterative histograms estimation procedure for finely tuning the channel estimation. Data is decoded during each iteration, based on a previous estimation of the channel during the previous iteration. If convergence is achieved, ISI optimization that maximizes the amount of ISI that is compensated by the MLSE is performed.Type: GrantFiled: August 7, 2014Date of Patent: September 19, 2017Assignee: Multiphy Ltd.Inventors: Omri Levy, Gilad Katz, Albert Gorshtein, Dan Sadot

Patent number: 9659185Abstract: A method for protecting user privacy in an online social network, according to which negative examples of fake profiles and positive examples of legitimate profiles are chosen from the database of existing users of the social network. Then, a predetermined set of features is extracted for each chosen fake and legitimate profile, by dividing the friends or followers of the chosen examples to communities and analyzing the relationships of each node inside and between the communities. Classifiers that can detect other existing fake profiles according to their features are constructed and trained by using supervised learning.Type: GrantFiled: March 21, 2013Date of Patent: May 23, 2017Assignee: B.G.

Patent number: 9628193Abstract: A method for estimating the phase of a modulated complex optical signal, according to which, the phase of the signal is isolated and the complex amplitude of the signal is digitized by a block of P samples. An adaptive filter minimizes phase-error between the phase of the received symbol and the phase of a sample, rotated by a phase correction factor, by iteratively performing a Block-Wise Phase LMS estimation on the samples using a step size parameter. During each iteration, the resulting correction factor consists of the sum of the estimated errors multiplied by this parameter, and the correction factor of previous iteration, which is updated, until obtaining the final correction factor from the last iteration. The samples constituting the received signal are recovered by adding the most updated correction factor to the phase of each sample and performing a decision regarding the phase of each sample.Type: GrantFiled: December 10, 2013Date of Patent: April 18, 2017Assignee: Multiphy Ltd.Inventors: Nir Sheffi, Gilad Katz, Albert Gorshtein, Ehud Barzilai, Dan Sadot

Publication number: 20170054533Abstract: An optical modulator with a region with non-linear characteristics with optimized BER performance, which comprises circuitry for adjusting the spacing between power levels of optical signals at the output of the optical modulator by adjusting the bias point of the optical modulator to be closer to a nonlinear region of the modulator, such that modulating signals having lower power will be compressed by the nonlinear region more than modulating signals having higher power. During adjustment, larger spacing between higher power levels of optical signals is introduced at the output of the optical modulator and lower spacing between lower power levels of optical signals is introduced at the output of the optical modulator.Type: ApplicationFiled: August 20, 2016Publication date: February 23, 2017Applicant: MULTIPHY LTD.Inventors: Eduard SONKIN, Gilad KATZ, Dan SADOT, Or VIDAL

Patent number: 9537578Abstract: Method and system for optimally equalizing distortion of an optical data channel carrying coherent optical signals with a given analog bandwidth B. A receiving end with IQ paths receives signals and a balanced detector detects signals in each path. The bandwidth of the detected signals is reduced by a factor of N by filtering the output of each path using an AAF with a cutoff frequency optimized to the analog bandwidth 2B/N of each path, where the AAF has deterministic attributes and introducing Known ISI. The signal is sampled at the AAF output by an ADC, at a sampling rate of 2B/N. The samples of each path are post-processed by a digital processor operating at a data rate of 2B/N, where post-processing represents the compensation of the distortion and the input data stream is reconstructed by optimally decoding the output of the processor using a decoder, which compensates the ISI.Type: GrantFiled: December 13, 2010Date of Patent: January 3, 2017Assignee: Multiphy Ltd.Inventors: Dan Sadot, Gilad Katz, Alik Gorshtein, Omri Levi

Publication number: 20160155145Abstract: A context-based recommendation process running in a cloud based system is presented. The process utilizes the capabilities of mobile communication networks and devices to provide businesses with the ability to supply sets of coupons to potential customers in a cost effective manner. The process uses real time and historical information that is provided by various sensors on a customer's smart mobile device to derive the customer's context. To make a recommendation, the system determines the current context of the customer and selects the right offer for the current context. The context is defined as both the external and internal environments in which the customer is active.Type: ApplicationFiled: November 25, 2015Publication date: June 2, 2016Inventors: Gilad KATZ, Asaf SHABTAI, Yuval ELOVICI, Matthias PROHL, Hamed KETABDAR
