之前已经在一些无线通信环境中测量了脉冲干扰。对于阵列中天线元件间隔很近的情况，缺乏基于物理的脉冲干扰模型。当采用空间处理时，这种情况很重要。在这些紧密间隔的元件情况下，干扰观测结果可能在统计上依赖于各个天线。这些紧密间隔的元素情况的模型是使用 David Middleton 最初提出的一些想法开发的。这里开发的模型非常通用，因此它似乎适用于各种物理情况。它假设干扰源在空间和时间上呈泊松分布，并且包括加性高斯背景分量。
Impulsive interference has been measured previously in some wireless communication environments. Physically-based impulsive interference models have been lacking for cases where the antenna elements in an array are closely spaced. Such cases are important when spatial processing is employed. In these closely-spaced element cases, the interference observations may be statistically dependent from antenna to antenna. A model for these closely-spaced element cases is developed using some ideas originally proposed by David Middleton. The model developed here is very general and so it appears to be applicable to a wide variety of physical situations. It assumes interference sources which are Poisson distributed in space and time, and it includes an additive Gaussian background component.
