Document Type and Number:
WIPO Patent Application WO/2016/192288
Kind Code:
A1
Abstract:
Provided is a method of a debugging conducted interference in a frequency modulated (FM) signal. The method comprises the following steps: if a FM antenna is in a disconnected mode, searching for a broadcasting station in an entire FM frequency band, collecting a received signal strength indicator of each of FM frequencies in the entire FM frequency band when the FM antenna is in the disconnected mode; determining whether the collected received signal strength indicator of each of the FM frequencies is within a standard strength range of a received signal at an FM frequency, if not, indicating presence of conducted interference and going to a next step; if so, indicating absence of conducted interference and returning to a previous step and continuing to collect a receiving signal strength indicator of each of the FM frequencies in the entire FM frequency band when the FM antenna is in the disconnected mode; searching for a conducted interference source, and performing, according to the conducted interference source, a debugging operation matching the conducted interference source. The present invention determines a source of a conducted interference by collecting an RSSI value of an FM and matching the connection or disconnection a matching circuit corresponding to an FM signal line, resulting in optimization of FM performance of an electronic apparatus, and providing a direction of adjusting and debugging the FM conducted interference.
