A terminal filtering method, system, device and filterable terminal

Abstract

The invention discloses a terminal filtering method, system and device and a filtering terminal. The method comprises following steps of when a terminal builds communication, obtaining the frequency of the signals transmitted by the terminal; calculating the harmonic waves of the transmitting signals according to the obtained frequency; judging whether the harmonic waves are in a frequency band of GPS signals of a global positioning system; when the harmonic waves are in the frequency band of the GPS signals, filtering the transmitting signals; and filtering the harmonic waves in the frequency band of the GPS signals. Through adoption of the scheme, the noise signals influencing a GPS can be filtered; the noises are prevented from being fed in an antenna and from being radiated out; the design demand on the antenna is reduced; and the design cost is reduced.

Description

technical field [0001] The present invention relates to the field of filtering, in particular to a terminal filtering method, system, device and filterable terminal. Background technique [0002] At present, more and more frequency bands are supported by the terminal. Therefore, the problem of electromagnetic dual-use between the GPS function of the terminal and the communication and data services of the terminal is becoming increasingly prominent. At present, the most common form of network communication is LTE Band13, that is, 4G network communication, which seriously interferes with GPS positioning. Users usually use 4G to access the Internet and affect the positioning of terminals. Moreover, in order to solve the electromagnetic interference problem of the terminal, the current solution is to do research on the antenna design, hoping to reduce the electromagnetic interference by improving the EMC compatibility of the antenna, but this undoubtedly increases the difficulty...
