The present invention discloses an apparatus and a method for improving a receiving sensitivity of a RF link belonging to the communication field. The apparatus includes a signal receiving module, a signal amplifying module and a signal processing module. The signal processing module receives a wireless communication signal and transmits the wireless communication signal to the signal amplifying module. The signal amplifying module amplifies the received wireless communication signal so as to acquire a first signal, and transmits the first signal to the signal processing module. The signal processing module demodulates the received first signal so as to acquire a second signal. The apparatus and the method solve a problem that: in related inventions, an RF module includes an antenna and a receiver connected to the antenna, a weak signal enters into the receiver through the antenna after being interfered, but the weak signal often can not be normally decoded. The apparatus and the method enhance an intensity of the signal received by the receiver and enable the received signal to be normally demodulated and decoded so as to acquire an effect of the demodulating signal with a low error rate.
Description
technical field [0001] The present disclosure relates to the communication field, in particular to a device and method for improving the receiving sensitivity of a radio frequency link. Background technique [0002] It has become a trend to use metal casings on mobile terminals. At present, many mobile terminals are designed according to the metallization of the whole machine. [0003] When the mobile terminal adopts an all-metal casing, it will interfere with the reception of wireless signals by the mobile terminal. In other words, the radio frequency module includes an antenna and a receiver connected to the antenna, and the weak signal after interference enters the receiver through the antenna. But this weak signal often cannot be decoded normally. Contents of the invention [0004] The present disclosure provides a device and method for improving the receiving sensitivity of a radio frequency link. The technical solution is as follows: [0005] According to the fi...
