Patent number: 10609582Abstract: A method for detecting interference in a wireless system is disclosed. The method includes receiving an uplink signal at a remote radio head in a distributed base station, passing the uplink signal from the remote radio head to a baseband unit over a front-haul communication link as baseband IQ data, and intercepting the baseband IQ data at a tester coupled between the remote radio head and the baseband unit. Processing of the IQ data is performed to determine whether an interfering signal is present in the uplink signal.Type: GrantFiled: August 30, 2017Date of Patent: March 31, 2020Assignee: CommScope Technologies LLCInventors: Ariful Hannan, Khalid W.
