Abstract

The invention discloses a radio system electromagnetic interference test system which is installed in a semi-anechoic chamber and comprises an amplitude modulation transmitter, a frequency modulationtransmitter, a receiver, a first transmitting antenna, a second transmitting antenna and a receiving antenna. The first transmitting antenna is connected with the amplitude modulation transmitter, thesecond transmitting antenna is connected with the frequency modulation transmitter, and the receiving antenna is connected with the receiver. The amplitude modulation transmitter is in communicationconnection with the receiver through the first transmitting antenna and the receiving antenna. The frequency modulation transmitter is in communication connection with the receiver through the secondtransmitting antenna and the receiving antenna. The amplitude modulation transmitter is installed at a first preset distance of the frequency modulation transmitter, and the receiving antenna is arranged at a position where the vertical distance between the amplitude modulation transmitter and the frequency modulation transmitter is a second preset distance. The invention also discloses a radio system electromagnetic interference test method, which can effectively eliminate other electromagnetic interferences in the space and reduce the hardware requirements of the test equipment, thereby effectively reducing the test difficulty and improving the accuracy of the test result.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a radio system electromagnetic interference testing system and method. Background technique [0002] With the rapid development of information construction, different electromagnetic interferences will be caused between radio equipment, and the radio equipment is developing in the direction of intelligence, integration, and complexity, so the problem of electromagnetic interference is very serious; modulation is very important in radio communication. It is important to study the problem of electromagnetic interference between transmitting devices of different modulations. At present, the test scheme of the transmission system is relatively complicated, and there are many test equipment used, and there are various types of electromagnetic interference in the wireless communication system, which makes the test difficult and the uncertainty of the test results is high...
