Patent number: 8238227Abstract: Systems and methods for reducing the latency and for increasing throughput for MoCA devices that are connected via a coax network are provided. One method according to the invention includes, in a network having a plurality of network modules, each of the plurality of network modules being connected to a coax backbone, communicating over the coax backbone between the plurality of network modules. The method further includes a requesting the use of short burst messages. The method further includes responding to the requesting by constructing a short burst message with a single channel equalization section and reducing the number of bits per hertz in the transmission constellation. The resulting messages can be received with an acceptable error rate while making more efficient use of the MoCA network.Type: GrantFiled: December 14, 2009Date of Patent: August 7, 2012Assignee: Broadcom CorporationInventors: Avraham Kliger, Eliahu Shusterman, Yitshak Ohana

Publication number: 20120093244Abstract: Apparatus, methods and systems for compensating for an I/Q imbalance may include compensating for an imbalance between a first component of a data signal and a second component of the data signal. The data signal may be modulated by a carrier signal having a frequency error. The first component may be characterized by at least one parameter. The method may include receiving the data and carrier signals; selecting a value for the parameter such that the frequency domain energy at negative frequencies is reduced; and modifying at least one of the components based on the value.Type: ApplicationFiled: October 4, 2011Publication date: April 19, 2012Applicant: Broadcom CorporationInventors: Zak Levi, Eliahu Shusterman

Patent number: 8098770Abstract: Apparatus and methods for estimating transmission noise in a programming information signal. Channel noise power in binary phase shift keying (“BPSK”) modulated telecommunication may be estimated. Such a method may include receiving over the channel a reference signal and a data BPSK signal. The data BPSK signal may include the programming information. The method may include formulating a channel transfer function estimate for the channel based on the reference signal. The estimate may include a channel estimation error. The data BPSK signal may be equalized using the transfer function estimate. The data BPSK signal may include noise, which may be quantified in terms of power. The data BPSK signal noise power may be estimated in such a manner that is independent of the channel estimation error.Type: GrantFiled: May 6, 2008Date of Patent: January 17, 2012Assignee: Broadcom CorporationInventor: Eliahu Shusterman

Patent number: 6987803Abstract: A receiver, for receiving a signal transmitted over a channel by a transmitter that includes a Tomlinson-Harashima precoder. The receiver includes a feed-forward equalizer (FFE), adapted to apply a feed-forward equalization function to the signal, so as to generate a sequence of equalized samples. A decision block is coupled to receive the equalized samples from the FFE and to generate a sequence of decision output samples responsive thereto, the decision block comprising an adaptive filter, having coefficients determined adaptively responsive to a characteristic of the channel. A Tomlinson-Harashima decoder is coupled to receive and decode the decision output samples so as to reconstruct the sequence of input symbols.Type: GrantFiled: July 26, 2001Date of Patent: January 17, 2006Assignee: Tioga Technologies, Inc.Inventors: Liron Frenkel, Eliahu Shusterman

Patent number: 6590933Abstract: A method for use in data communications equipment for improving convergence of a hybrid decision feedback apparatus including an adaptive feed-forward equalizer and an adaptive decision feedback equalizer. An independent error predictor component is used for better convergence and then is eliminated by converting, using z-transformations, the adaptive feed forward equalizer and adaptive decision feedback equalizer to an equivalent feed forward equalizer and an equivalent decision feedback equalizer, respectively, in which the error predictor is embedded or incorporated therein. The smaller system with a reduced number of FFE-DFE coefficients has a faster convergence rate.Type: GrantFiled: December 27, 1999Date of Patent: July 8, 2003Assignee: Tioga Technologies Ltd.Inventors: Eliahu Shusterman, Ehud Rokach, Lior Mishan
