Patent number: 10673658Abstract: A circuit in a wireless communications terminal/device and a method is described for reducing an image distortion. By measuring three gain mismatches of I path and Q path of a transceiver, and estimating a value of an IQ mismatch coefficient based on the three gain mismatches; and applying a measurement adjustment to the I path or the Q path based on the value of the IQ mismatch coefficient, the image distortion is reduced.Type: GrantFiled: July 8, 2019Date of Patent: June 2, 2020Assignee: Futurewei Technologies, Inc.Inventors: Hong Jiang, Jamil Mark Forrester, Zhihang Zhang
