Description

technical field [0001] The invention relates to the field of electromagnetic compatibility design in wireless communication, in particular to a small base station electromagnetic interference identification method. Background technique [0002] The composition of modern communication equipment system is complex, which is characterized by highly integrated system, diverse signal system, complex circuit structure and numerous components. Different electronic devices produce various types of electromagnetic emissions, which exceed the limit levels of various standards, causing serious electromagnetic interference problems. Due to the diverse forms of electromagnetic interference, it is difficult to clarify the types of interference sources one by one, which brings difficulties to electromagnetic compatibility design. The traditional method of analyzing electromagnetic compatibility problems is to find the source of electromagnetic interference based on the test results, and th...

Problems solved by technology

This requires designers to have rich engineering experience and a good understanding of the equipment circuit structure. At the same time, the process of determining the source of electromagnetic interference is often repetitive, which requires a lot of manpower and material resources, thus prolonging the design cycle and increasing the design cost.

Traditional EMC analysis methods have great limitations, and solutions to EMC problems are less portable
