Patent number: 11838038Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transceiver chain may receive, using a downconverter tuned by at least one local oscillator, transmit signals that are modulated using a modulation bandwidth and that span a total bandwidth greater than or equal to the modulation bandwidth. The at least one local oscillator may cover a first fraction of the total bandwidth. The transceiver chain may receive, using at least one analog-to-digital converter, input from the downconverter, and may output a first digital signal based at least in part on the input and sampling at the first fraction of the total bandwidth. The transceiver chain may determine an error associated with the transmit signals based at least in part on the first digital signal, and may perform digital pre-distortion on new signals based at least in part on the error. Numerous other aspects are described.Type: GrantFiled: May 3, 2021Date of Patent: December 5, 2023Assignee: QUALCOMM IncorporatedInventors: Nicholas Michael Carbone, Shubham Ahuja, Aidin Bassam, Alexander Dorosenco

Patent number: 9490855Abstract: Embodiments include systems and methods for managing an adaptive interference filter performed by a device processor of a mobile communication device. A device processor may determine whether a transmission power from the mobile communication device is greater than or equal to a transmit power threshold. The device processor may determine whether a ratio of interference in a received signal to a level of the received signal including noise (interference ratio) is greater than or equal to an interference ratio threshold in response to determining that the transmission power is greater than or equal to the transmit power threshold. The device processor may perform interference cancellation with the adaptive interference filter in response to determining that the interference ratio is greater than or equal to the interference ratio threshold. In some embodiments the adaptive interference filter may be a non-linear interference cancellation filter.Type: GrantFiled: September 1, 2015Date of Patent: November 8, 2016Assignee: QUALCOMM IncorporatedInventors: Roberto Rimini, Nicholas Michael Carbone, Taesang Yoo, Muhammad Abdelghaffar, Sung Hwang, Wooseok Nam

Publication number: 20160072591Abstract: The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a block least squares function interference filter by generating aggressor kernel matrices from the aggressor signals, augmenting the aggressor kernel matrices by weight factors and executing a linear combination of the augmented output, at an intermediate layer to produce intermediate layer outputs. At an output layer, a linear filter function may be executed on the intermediate layer outputs to produce an estimated nonlinear interference used to cancel the nonlinear interference of a victim signal.Type: ApplicationFiled: September 9, 2015Publication date: March 10, 2016Inventors: Sheng-Yuan TU, Farrokh Abrishamkar, Brian Clarke Banister, Roberto Rimini, Nicholas Michael Carbone, Insung Kang

Publication number: 20150311929Abstract: A communication device can independently determine an interference magnitude component and an interference phase component for interference cancellation. The interference magnitude component may be estimated based, at least in part, on a magnitude polynomial expansion and a transmit signal of the communication device. The interference phase component may be estimated based, at least in part, on a phase polynomial expansion and the transmit signal. The magnitude polynomial expansion and the phase polynomial expansion may have different polynomial terms. The interference signal may be determined based, at least in part, on the interference magnitude component and the interference phase component. At least a portion of the interference signal may be cancelled from a receive signal received by the communication device.Type: ApplicationFiled: April 24, 2014Publication date: October 29, 2015Applicant: QUALCOMM IncorporatedInventors: Nicholas Michael Carbone, Roberto Rimini, Jibing Wang

Patent number: 9166635Abstract: Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. A victim receiver may obtain a non-linear interference cancelation (NLIC) signal from an aggressor transmitter of a communication device. The NLIC signal may be based, at least in part, on a source transmit signal that has been distorted by digital pre-distortion (DPD) at the transmitter. An NLIC unit may reconstruct a cancelation signal based on the NLIC signal. A receiver may remove the cancelation signal from a received signal.Type: GrantFiled: March 18, 2014Date of Patent: October 20, 2015Assignee: QUALCOMM IncorporatedInventors: Nicholas Michael Carbone, Roberto Rimini

Patent number: 8718178Abstract: Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. An aggressor transmitter may provide two or more non-linear interference cancelation (NLIC) signals, including a first NLIC signal and a second NLIC signal. A NLIC unit may reconstruct an interference signal based on a selected one of the first NLIC signal or second NLIC signal. Power of the transmitted signal at the aggressor transmitter may be used to select either the first interference cancelation signal or the second interference cancelation signal. The first and second NLIC signals may differ by the use of digital pre-distortion (DPD) at the aggressor transmitter.Type: GrantFiled: November 8, 2013Date of Patent: May 6, 2014Assignee: QUALCOMM IncorporatedInventors: Nicholas Michael Carbone, Roberto Rimini

Publication number: 20080268779Abstract: A victim wireless device is detected by obtaining a set of wireless bands and a set of time periods. During a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data. During each of the time periods in the set of time periods: a signal, if any, is received; in the event a signal is received, the subset of vacant wireless bands corresponding to that time period is recorded; and after the set of time periods ends, it is determined whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.Type: ApplicationFiled: March 31, 2008Publication date: October 30, 2008Inventors: Sandeep Rajpal, Siddharth Shetty, Gaetano Roberto Aiello, Timothy Leo Gallagher, Nishant Kumar, Nicholas Michael Carbone, James Laurence Taylor
