[0004] However, if the shielding device is set on the surface of the mobile terminal, the data receiving interface, such as the LCD display interface and the antenna, need to be respectively arranged at the two ends of the mobile terminal. At this time, the LCD display interface and the camera in the mobile terminal are arranged at the same end, so that the mobile Increased terminal thickness
At the same time, when the bandwidths of the digital signal and the noise signal are close, the filtering method cannot filter out the noise signal

Embodiment Construction
[0050] The inventors have found through research that since the high-level signal contains high-frequency signals, the high-level signal will be radiated in the form of radio waves during transmission, which will interfere with the antenna, thereby affecting the receiving sensitivity of the antenna.
[0051] Furthermore, when the number of high-level signals transmitted on the data line is greater than the number of low-level signals, the signal power increases. If the length of the data line exceeds one-tenth of the wavelength of the electromagnetic wave, the signal with higher power will also be radiated in the form of radio waves, which will increase the interference to the antenna and affect the receiving sensitivity of the antenna. Therefore, in order to solve the impact on the receiving sensitivity of the antenna during signal transmission, the present application proposes a signal processing method.
[0052] The signal processing method is different from the shielding a...

The invention provides a method, a system of signal processing and a mobile terminal. The signal processing method comprises the steps that levels of signals transmitted by at least two data lines are detected, and a group of first data lines transmitting high-level signals and a group of second data lines transmitting low-level signals; a first number and a second number are counted; whether the first number is larger than the second number is adjusted and an adjustment result is acquired; when the adjustment result indicates that the first number is larger than the second number, data lines in the group of the first data lines are controlled to transmit high-level signals, and data lines in the group of the second data lines are controlled to transmit low-level signals so as to reduce signal power, and accordingly prevent signals from interfering with an antenna, improve receiving sensitivity of the antenna, reduce affects of noise signals on communication channels and improve communication quality of the mobile terminal. Furthermore, when the signal processing method is applied to the mobile terminal, devices in the mobile terminal can be randomly arranged so as to reduce the thickness of the mobile terminal.
Description
technical field [0001] The present application relates to the technical field of digital signal processing, and in particular to a signal processing method, system and mobile terminal. Background technique [0002] With the development of technology, the functions of mobile terminals are becoming more and more powerful, such as large screens, high-pixel cameras, and large memories. However, with the increase of functions, the integrated digital circuits in the mobile terminal become larger in size and complex in structure. However, when the integrated digital circuit in the mobile terminal works, it will generate noise, thereby reducing the receiving sensitivity of the antenna in the mobile terminal, further affecting the communication quality of the mobile terminal, such as causing poor communication. [0003] At present, in order to avoid the influence of noise on the receiving sensitivity of the antenna in the mobile terminal, a combination of shielding and filtering is ...
