EMC (Electromagnetic Compatibility) comprehensive forecasting and analyzing system for common-address interference of analog radio station

Abstract

The invention relates to electromagnetic compatible forecast, in particular to an EMC (Electromagnetic Compatibility) comprehensive forecasting and analyzing system for common-address interference of an analog radio station. The system at least comprises a work radio station unit emitter, a work radio station unit receiver, an interference radio station unit emitter, a coupling channel unit, a channel unit and an SINAD (Signal-to-Noise-and-Distortion) unit. The work radio station unit emitter is used for transmitting a processed information source to a modulating unit and then emitting the information source by a radio frequency signal with a certain power after the information source modulated by the modulating unit; the work radio station unit receiver is used for transmitting the received radio frequency signal to a demodulating unit for demodulation and then transmitting to an output unit after the received radio frequency signal is demodulated by the demodulating unit; the interference radio station unit emitter is used for generating an interference signal with radiation emitting property and limit emitting power; and the coupling channel unit is an interference channel arranged between the interference radio station unit emitter and the work radio station unit receiver and is used for coupling the interference signal of the interference radio station unit emitter to the channel unit. The invention provides the EMC comprehensive forecasting and analyzing system for the common-address interference of the analog radio station in coexistence with analog communication.

Description

technical field [0001] The invention relates to electromagnetic compatibility prediction, in particular to an EMC comprehensive prediction and analysis method for co-site interference, in particular to an EMC comprehensive prediction and analysis system for simulating radio station co-site interference. Background technique [0002] With the increasing integration of communication equipment, a single vehicle often serves as the same node of multiple wireless networks at the same time. Therefore, there are many types of wireless devices in the car, especially various radio stations. However, due to the limited space on the top of the vehicle, the coupling between the antennas of each radio station is very strong, resulting in very serious co-site interference problems. Compared with external man-made interference, co-location interference has a greater magnitude of interference, especially when multiple radio stations work at the same time, it will lead to more serious mutual...

Therefore, there are many types of wireless devices in the car, especially various radio stations. However, due to the limited space on the top of the vehicle, the coupling between the radio stations through the antennas is very strong, resulting in very serious co-site interference problems.

Compared with external man-made interference, co-location interference has a larger interference level, especially when multiple radio stations work at the same time, it will lead to more serious mutual interference in the system and directly affect communication performance
