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...
