Abstract

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.

阵列观测中基于物理的脉冲噪声模型

在一些无线通信环境中，脉冲干扰已经被测量过了。对于阵列中天线单元间隔很近的情况，缺乏基于物理的脉冲干扰模型。当使用空间处理时，这种情况很重要。在这些距离很近的单元情况下，从天线到天线的干扰观测可能在统计上是依赖的。使用David Middleton最初提出的一些想法，开发了这些紧密间隔元素情况的模型。这里开发的模型是非常普遍的，因此它似乎适用于各种各样的物理情况。它假设干扰源在空间和时间上为泊松分布，并包含一个加性高斯背景分量。
