Abstract

The embodiment of the invention provides an antenna multiplexing method, a device and a wireless terminal. The method comprises the following steps of: choosing paths for wireless signals acquired by antennas of the wireless terminal through an antenna multiplexer according to a frequency range; and transmitting the wireless signals subjected to the path choce to corresponding antenna matching circuits so that the antenna matching circuits match the wireless signals and send the wireless signals into corresponding radio frequency paths. The embodiment of the invention not only can reduce the quantity of the antennas of the wireless terminal, but also can avoid mutual interference between signals with different frequencies.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an antenna multiplexing method, device and wireless terminal. Background technique [0002] With the development of wireless communication technology, wireless terminals, including mobile phones, fixed network and mobile network convergence (FMC, Fixed Mobile Convergence) equipment, data cards, etc. are becoming more and more integrated, and product design is becoming more and more complex. Multiple wireless system designs often need to be implemented within the product space. [0003] Taking a mobile phone as an example, multiple wireless systems such as a wireless wide area network (WAN), a wireless local area network (WIFI, Wireless Fidelity), and a global positioning system (GPS, Global Position System) can be integrated inside the mobile phone. In addition, in order to improve the wireless performance of communication, a diversity receiving circuit is o...
