Abstract

The embodiment of the invention provides an antenna switching method, a receiving device and a terminal. The method comprises the following steps: measuring the signal receiving quality of a first antenna; determining a target antenna of which the signal receiving quality is higher than the signal receiving quality of the first antenna from at least one second antenna under the situation that the signal receiving quality of the first antenna is determined to be lower than a preset first threshold, wherein the target antenna is an antenna which is determined firstly by comparison and has higher signal receiving quality than the first antenna; and switching the first antenna which is currently coupled with a receiver to the target antenna in order to receive wireless signals through the target antenna. Through adoption of the antenna switching method, the receiving device and the terminal provided by the embodiment of the invention, early exit from a comparing stage can be realized; the comparison time is shortened; the antenna selection time is further shortened; and an available antenna can be found rapidly.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna switching method, a receiving device, and a terminal. Background technique [0002] In the field of mobile terminals, in order to obtain a better appearance design, more and more manufacturers use metal casings. Different positions of users holding mobile terminals or metal casings will affect the antenna performance of mobile terminals. In order to solve this problem, Usually, a main antenna and a secondary antenna are set on the mobile terminal to work together, and some even have three or four antennas. Moreover, with the development of Long Term Evolution (LTE for short) data services, the multi-antenna technology can provide rich communication services. [0003] For multi-antenna mobile terminals, antenna optimization algorithms are currently used to select antennas. Specifically, it is necessary to find the antenna with higher...
