Patent number: 9148328Abstract: An apparatus and method reduce distortion in a processed signal. The apparatus includes a first receive path, a second receive path, a summation unit, and a compensation unit. The first receive path is configured to process a received analog signal into a first digital signal. The second receive path is configured to process the received analog signal with a phase shift into a second digital signal. The summation unit is configured to sum the first and second digital signals to form a processed digital signal. The compensation unit is configured to identify a conjugate of the processed digital signal, apply a weighting factor to the conjugate of the processed digital signal to form a weighted signal, and subtract the weighted signal from the processed digital signal to reduce the distortion.Type: GrantFiled: October 26, 2011Date of Patent: September 29, 2015Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Yaming Zhang, John Alexander Interrante, William Hurley, Lup M.

Patent number: 7391256Abstract: The present disclosure relates generally to systems and methods for direct current (DC) correction in wireless devices. In one example, a method includes setting a cutoff frequency of a filter at a first frequency, where a signal entering the filter is attenuated based on the cutoff frequency. If a qualified change is detected in a DC component of the signal, the cutoff frequency is set at a second frequency that attenuates more of the signal than the first frequency for a defined time period. The cutoff frequency may then be set to the first frequency after the defined time period.Type: GrantFiled: September 18, 2006Date of Patent: June 24, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: William Milton Hurley, Lup Meng Loh, Yinong Ding, Michael L.

Patent number: 6011783Abstract: A method and apparatus for monitoring the performance of an echo canceler within a telephone communications network is disclosed. In accordance with the method and apparatus of the present invention, an embedded echo-cancellation performance monitoring circuit comprises three separate units, namely, a test data injection unit, an echo path simulator unit, and a test data extraction unit. The test data injection unit is utilized to inject test data into a serial data stream intended for an echo canceler. The echo path simulator unit is utilized to simulate an echo path by attenuating the test data in the serial data stream and to loop the test data in the serial data stream back to the echo canceler. The test data extraction unit is utilized to extract the test data from a send-out data stream exiting from the echo canceler.Type: GrantFiled: June 11, 1997Date of Patent: January 4, 2000Assignee: Nortel Networks CorporationInventors: John Alexander Interrante, Tomas Perez Morales
