摘要
在有微波炉辐射干扰的情况下,许多工作在ISM频段的无线通信系统出现了性能严重下降的情况.为解决这一问题,本文首先分析微波炉干扰在时域和频域呈现的特性,并在Middleton的标准"A类冲击性噪声模型"的基础上,根据微波炉辐射干扰的一阶统计特性,为微波炉的辐射干扰建立模型.然后在这一模型的基础上,研究无线通信系统的最佳接收方案.
The performance of digital radio communication systems working at ISM frequency band is much degraded by the effect of microwave oven interference. Therefore, to solve this problem, we firstly analyze the characteristics of microwave oven interference in the time and frequency domain, then we propose a statistical model of microwave oven interference according to the first order statistic of microwave oven interference by using Middleton's canonical class_A impulsive noise model. At last, based on this model, we should design a new way of optimum receiver for digital radio communication systems.
