| 摘 要： | 提出了通信装备系统间互扰评估的一种低计算复杂度分析方法。比特差错概率是对数字通信接收机性能进行评估的重要指标,而由比特差错概率(BEP)表征的系统间互扰的情况计算非常复杂,因此需要合理简化。通常假设干扰为加性高斯白噪声,但有些情况下这种假设并不合理。而使用高阶统计量峰度值来估计的方法可以处理调制干扰信号也可以处理脉冲干扰信号,综合了加性高斯白噪声近似和峰度测量以达到对数字通信设备间互扰分析更合理精确。

| Abstract: | The paper puts forward an analytical low-complexity method for intersystem interference estimation among communication equipment.BEP is normally employed to estimate the function of the digital communication receivers but simplification is needed in computing and analyzing for the reason that the circumstances of the intersystem-interference via BEP are extremely complicated.The interference is often supposed to be AWGN,while in some cases it is not reasonable supposition.So the method based on HOS kurtosis is proposed.Integrating AWGN approximate and kurtosis measurement,it can deal with both modulated interference signals and impulse interference signals so as to achieve more accurate and reasonable analysis of the interference among digital communication equipment. |

| Keywords: | intersystem-interference higher-order statistics(HOS) kurtosis |
