###### Abstract
The above research can be extended to the EMC analysis of different types of systems. Through analyzing the electromagnetic characteristics of CW of high and low power, the authors in [25; 26] studied the typical performance and the sensitive characteristics of the receiver under CW interference environment. The electromagnetic environment confronted by the receiver is dynamic and diverse. Therefore, the dynamic integrity construction of the electromagnetic environment in the test stage is particularly important for the EMC evaluation of the receiver. Starting from the physical characteristics of electronic equipment and the coupling mechanism of space electromagnetic field acting on electronic equipment, the theoretical method of EMC element set was proposed in [27]. The authors in [28] proposed the concept of the complexity degree of the electromagnetic environment and tried to use it to evaluate the interference signal. Starting from the response of typical ports to electromagnetic environment, the authors in [29] proposed a novel equivalent construction method of electromagnetic environment and EMS threshold test method. The accuracy and engineering applicability of the proposed method are verified by theoretical and experimental analysis. The EMC of receiver usually needs to be analyzed and evaluated according to the results of radiation sensitivity (RS) test and conduction sensitivity (CS) test. The different coupling mechanisms and advantages of RS and CS test are analyzed through the research of experiment and modeling methods [30; 31; 32; 33; 34]. The EMC evaluation of electronic systems are inseparable from theoretical analysis and experimental test. The measurement data and theoretical model, measurement data and numerical simulation results, measurement data and standard specifications will bring uncertainty to EMC evaluation. Therefore, through the statistical evaluation of test results and the uncertainty quantification of random variables, the accuracy and reliability of EMC evaluation of electronic systems could be improved [35; 36; 37; 38]. We believe that the existing research has mainly analyzed the characteristics of pulse signals in the time domain, frequency domain and energy domain. Through simulation and testing, the analysis of the receiver EMS effect and EMC evaluation under a pulsed interference environment is carried out from the perspective of energy (usually the signal power received in the receiver's working frequency band, which can range from a 3 or 6 dB bandwidth depending on the receiver's performance index) for specific scenarios. However, the impact of the electromagnetic parameters of pulse signals on electronic systems has not been well understood. There is a lack of analysis and quantitative characterization of the EMI effect of typical parameters of pulse signals on receivers, which is difficult to meet the requirement of receiver EMC evaluation under dynamic and diverse environment. Inspired by previous research, in this paper, we select the BER as the typical performance index of the receiver. By analyzing the electromagnetic characteristics of the pulse signal, we carry out the quantitative characterization modeling of the interference effect of the receiver based on BER. Based on characterization of BER, a novel EMC test and evaluation method for the receiver under pulsed interference environment is proposed in this paper. The accuracy and engineering applicability of the proposed model and method are verified by numerical simulation and experimental analysis. The novelty of this paper is embodied into two major aspects. On the one hand, based on the electromagnetic characteristics of pulsed interference signals, the modeling approach for quantitative characterization of receiver interference effect under pulsed environment is carried out. By establishing the quantization relationship between BER and pulse width, repetition period, ISR, duty cycle and signal period, the generalized receiver interference effect quantization characterization model is constructed.
