Abstract

The invention provides a signal receiving path switching method and a mobile terminal. The method comprises steps as follows: acquiring signal intensity and a first switching threshold value of a downlink signal received through a first receiving path; controlling the mobile terminal to be switched from the first receiving path to a second receiving path when the signal intensity of the downlink signal is smaller than the first switching threshold value and receiving the downlink signal through the second receiving path; a filter is included in the first receiving path, and not included in the second receiving path. With the adoption of the signal receiving path switching method and the mobile terminal, the receiving sensitivity of the downlink signal can be improved, better downlink communication quality can be realized, the code rate is increased, the retransmission rate is reduced, electricity consumed by repeated receiving can be saved, the communication distance can be increased, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for switching a signal receiving path and a mobile terminal. Background technique [0002] In the communication system, filters such as SAW (Surface Acoustic Wave, Surface Acoustic Wave filter) or BAW (Bulk Acoustic Wave, Bulk Acoustic Filter Wave) are usually added to the signal receiving path, and the filter can suppress the noise outside the receiving frequency band. Strong noise, avoid strong noise causing LNA (Low Noise Amplifier, Low Noise Amplifier) ​​saturation, avoid out-of-band strong noise entering the LNA to generate intermodulation products and fall on the receiving frequency band, so as to avoid affecting the receiving performance. In the signal receiving path where the filter is added, the filter has inevitable insertion loss, and the port impedance is not converged enough due to the filter, which will cause a certain attenuation to the reception of...
