The Complexity Evaluation Method of Electromagnetic Environment Based on Statistical Characteristics Analysis

Abstract:

An objective complexity evaluation method of electromagnetic environment is presented based on statistical characteristics analysis. In order to quantize variation characteristics and statistical law of electromagnetic environment, evaluation factors are introduced such as relative variation, average variational ratio, maximum variational ratio, standard deviation and skewness of power spectral density. Besides, evaluation factors such as time occupancy, spectrum occupancy, space occupancy and Average energy value are utilized to conduct the objective evaluation comprehensively and accurately in time, frequency, space and energy domains. The practicability of this method is validated by monitoring data. Results show that this method can effectively evaluate the complexity of electromagnetic environment.
