结果表明，这些影响的金额可以推导出使用一对加权函数的相位噪声的频谱。这些加权函数的使用简化了计算过程;它还使得对相位噪声频谱的任何修改的结果更容易可视化。给出了两种相位噪声对DVB-T数字电视信号星座图的影响的一些说明，沿着了对接收器实现的一些实际观察。
It is shown that the amounts of these effects can be deduced from the spectrum of the phase noise using a pair of weighting functions. Use of these weighting functions simplifies the process of computation; it also makes it easier to visualize the consequences of any modifications to the phase-noise spectrum. Some illustrations are given of the two phase-noise effects on the constellation of a DVB-T digital television signal, along with some practical observations on receiver implementation.
