摘要
在分析无线通信环境中脉冲干扰特征及其对无线通信影响的基础上,提出利用修正周期图功率谱密度和NP定理对周期性脉冲干扰进行干扰检测的策略与脉冲周期及占空比等参数测量的方法。在给定虚警率指标下,推导并计算了周期性脉冲干扰检测的概率,并通过实验仿真验证了采用本文所提策略检测周期性脉冲干扰的有效性和准确性。
Based on the analysis of the characteristics of pulsed jamming in wireless communication and its impact on wireless communication, a strategy for detecting the periodic pulsed jamming by using the power spectral density of the modified periodic pattern and Non-deterministic Polynomial(NP) theorem is proposed, and the method for measuring the parameters of pulse period and duty cycle is also presented. The probability of periodic pulsed jamming detection is deduced and calculated under the given false alarm rate index. The effectiveness and accuracy of the proposed strategy for detecting periodic pulsed jamming are verified through experimental simulation.
