Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.
[0023] Such as figure 1 As shown, the first embodiment of the present invention relates to a method for automatically adjusting channel gain. The method for automatically adjusting channel gain is mainly performed by an automatic channel gain adjusting system. The automatic adjustment system adjusts the carrier-to-noise ra...

The invention relates to the field of wireless communication, and discloses an automatic adjustment method and system of channel gain and applicable mobile equipment. According to the method, the system ergodically adjusts the gain of the channel according to the preset gain control level, and calculates the carrier-to-noise ratio of the channel after each adjustment; then according to the maximum value of the calculated carrier-to-noise ratios The corresponding gain control level is used to control the gain of the channel until the gain obtained according to the determined gain control level exceeds a preset range, and the gain of the channel is readjusted. The present invention traverses all the gain levels to select a gain amplification ratio that maximizes the carrier-to-noise ratio of the channel to process the received channel signal, and can obtain a mobile device with a high-sensitivity signal.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to an automatic adjustment method and system for channel gain and applicable mobile equipment. Background technique [0002] With the improvement of the intelligence of mobile devices, it is very common to use mobile devices for navigation. Signals such as GPS used for navigation are very small and often interfered with by other signals. When the user needs to surf the Internet or make a phone call while navigating, the channel occupied by the mobile data network and the phone will strongly interfere with the navigation signal. In this case, if the navigation signal is still amplified with a fixed low gain, the interference signal must be amplified together, so that the sensitivity of the receiver of the navigation signal in the mobile device is limited. [0003] At present, the commonly used method is to monitor whether the mobile device receives a GSM signal with high power...
