Abstract
Disclosed are an electronic device and a method of controlling a spurious emission. A spurious emission is identified by setting a first time interval in which a feedback receiver operates in a spurious emission detection mode, and identifying a spurious emission from the electronic device by analyzing a feedback signal obtained by the feedback receiver based on a first resolution bandwidth and a second resolution bandwidth in the first time interval.
Claims18
An electronic device comprising:
- a memory storing instructions;
- and
- at least one processor electrically connected to the memory and configured to execute the instructions,
- wherein, based on the instructions being executed by the at least one processor, the at least one processor causes the electronic device to control a plurality of operations, and
- wherein the plurality of operations comprises:
- setting a first time interval in which a feedback receiver operates in a spurious emission detection mode,
- obtaining a feedback signal in a first frequency band via the feedback receiver based on a first resolution bandwidth in the first time interval,
- determining whether a spurious emission is in the frequency band by analyzing the feedback signal, and
- in response to determination that the spurious emission is in the frequency band, determining whether a spurious emission is in a second frequency band included in the first frequency band based on a second resolution bandwidth narrower than the first resolution bandwidth,
- wherein the feedback signal corresponds to a radio frequency (RF) signal amplified by a power amplifier of the electronic device.
A method of determining a spurious emission of an electronic device, the method comprising:
