Patent number: 10348449Abstract: A method includes processing error correction encoded data by a first processing chain of a transmitter. The processing includes interleaving a first portion of the error correction encoded data with respect to a first interleaving period to generate a first output signal. Interleaving the first portion includes de-multiplexing the first portion among multiple branches having respective delays in accordance with a distribution order and re-multiplexing delayed data from the branches to form the first output signal. The method includes processing the error correction encoded data by a second processing chain of the transmitter without use of interleaving to generate a second output signal. The method includes multiplexing the first output signal and the second output signal into a multiplexed stream. The method also includes transmitting the multiplexed stream from the transmitter over a communication channel to a receiver.Type: GrantFiled: October 3, 2017Date of Patent: July 9, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Doron Rainish, Ilan Saul Barak, Raz Shani

Patent number: 7420950Abstract: A method for communication in a sequence of frames includes assigning a respective time slot to each of a plurality of mobile units, while reserving an unassigned time slot. During a first frame, one of the mobile units transmits an uplink signal in the respective time slot, carrying first uplink data over the air to a base station. The base station transmits a downlink signal to the mobile unit indicating that retransmission of the first uplink data is required. Responsively to the downlink signal, during a second frame subsequent to the first frame, the mobile unit transmits the uplink signal both in the respective time slot and in the reserved time slot so as to carry the first uplink data and second uplink data over the air to the base station. A similar method may be used for downlink retransmission.Type: GrantFiled: April 5, 2004Date of Patent: September 2, 2008Assignee: DSPG Ltd.Inventors: Ilan Saul Barak, Ofer Shneyour

Publication number: 20040076247Abstract: A method for processing an input signal having an input peak-to-average (PAR) so as to generate an output signal having an output PAR and a permitted spectral mask. The method includes generating a difference signal proportional to an amount by which the input signal exceeds a predetermined threshold, and filtering the difference signal with a filter having a spectral response that is determined responsively to the permitted spectral mask. The filtered difference signal is subtracted from the input signal to generate the output signal so that the output PAR is adjusted relative to the input PAR. Typically, the output PAR is reduced relative to the input PAR.Type: ApplicationFiled: October 22, 2002Publication date: April 22, 2004Applicant: WISEBAND COMMUNICATIONS LTD.Inventors: Ilan Saul Barak, Yuval Shalom, Nir Tal
