| 摘 要： | 目前,微波通信的特点是数字微波方式与频分多路调频(FDM-FM)方式并存,通常FM方式比数字无线方式发信电平高10dB左右,为实现符合指标要求的通信,必须找出FM方式对数字无线方式干扰特性的分析方法,以便作出正确的评价。本文将FM干扰波设定为正弦波,并迭加有高斯分布的热噪声时,对误码率的影响进行了评价。另外,本分析方法将FM干扰波分为载波分量与边带波分量,这样比较符合实际电路的结果。

| Abstract: | At present,the characteristic of the microwave communication is the computibility of digital microwave mode and frequency division multiplet-frequency mode (FDM-FM). As usual,the signalling level of FM mode is higher then of digital radio mode by 10dB. To implement the communication according with standard, we should find out the analysis method about interference characteristic with FM mode forward digital radio mode so as to make a correct assessment.In this paper, we let interference wave be sinusoidal wave considering the additional thermal noise,which is gaussian distribution, will take a influential on assessing error code rate. Secondly, this analysis method divides FM interference wave into carrier component and side wave component to assess result,which is more coincide with the result of factual circuit. |
