Complex electromagnetic signal environment construction method in communication device adaptability test

Abstract

A complex electromagnetic signal environment construction method in a communication device adaptability test mainly solves the problem that a vivid complex electromagnetic signal environment needed for the test is difficult to construct during the indoor test of adaptability to electromagnetic environment of a wireless communication electronic device. According to the method, a physical communication device, a signal simulator, and a signal simulation model are combined together to construct an indoor complex electromagnetic signal environment, the indoor complex electromagnetic signal environment has real characteristics of the physical device signal and can make up for shortage of the numberof the physical devices and technical defects in the prior art through a way that signal simulation model operating data files are loaded to a signal playback device to generate radio-frequency signals, and the requirements of construction of the electromagnetic environment in the test of adaptability to complex electromagnetic signal environment of the wireless communication electronic device can be met.

Problems solved by technology

[0008] The above-mentioned construction methods, the disadvantage of the first method is: when the electromagnetic environment required for construction is complex and changeable, the number of physical equipment and signal simulators required increases sharply, and it takes a lot of time to develop and rent these equipment and simulators. Manpower, financial and material resources, the economic investment is very large, sometimes even unbearable

[0009] The disadvantage of the second method is that in the process of modeling various signals and performing relevant mathematical processing for electromagnetic environment signal modeling, it takes a long time to develop, especially in signal model design, model debugging, simulation operation control, etc. And verification, the requirements for personnel quality, technical research, etc. are very high, and the requirements for the research of various signal activity mechanisms in the electromagnetic environment are higher, which leads to high difficulty in modeling more complex signal environments, and the accuracy and precision of the model. Difficult to guarantee, the authenticity of the constructed electromagnetic environment is low
