在这篇文章中，严格的和普遍的界限已被导出的正交频分复用（OFDM）信号的信道间干扰（ICI）所造成的多普勒扩展。通用的界限仅取决于最大多普勒频率和OFDM符号持续时间的乘积。紧界还取决于多普勒频谱的方差。与其他研究人员推导的ICI表达式相比，这些边界更容易评估，并可以提供有用的见解。
In this article, tight and universal bounds have been derived for the interchannel interference (ICI) of an orthogonal frequency-division multiplexing (OFDM) signal resulting from Doppler spread. The universal bound depends only on the product of the maximum Doppler frequency and the OFDM symbol duration. The tight bound also depends on the variance of the Doppler spectrum. Compared with the exact ICI expressions derived by other researchers, these bounds are easier to evaluate and can provide useful insight.
