正交频分复用（Orthogonal Frequency Division Multiplexing，OFDM）信号具有高子载波数的近似高斯特性，这一特性被广泛用于描述非线性失真的OFDM信号并评估其性能。在本文中，我们研究了高斯方法的准确性时，在有限个子载波的OFDM信号的非线性效应的评估，显示这种方法的优势和局限性。
The almost Gaussian nature of OFDM (Orthogonal Frequency Division Multiplexing) signals with high number of subcarriers is widely employed to characterize nonlinearly distorted OFDM signals and to evaluate the corresponding performance. In this paper we study the accuracy of the Gaussian approach when evaluating nonlinear effects in OFDM signals with finite number of subcarriers, showing the strengths and limitations of this approach.
