摘要

本文提出了一种严格的OFDM信号量化分析方法。ADC输出端的信噪比是作为输入信号的标准偏差和ADC输入范围的函数推导出来的。此外，还计算了各种ADC分辨率下的最大信噪比。利用OFDM无线局域网信号和正态分布高斯白噪声进行仿真，验证了分析结果。

Analytic quantization modeling of OFDM signals using normal Gaussian distribution

This paper presents a rigorous analytic approach for the quantization of OFDM signals. The signal-to-noise ratio at the ADC output is derived as a function of the input signal's standard deviation and the ADC input range. Furthermore, the maximum signal-to-noise ratio is calculated for various ADC resolutions. The analytic results are verified by simulations applying an OFDM WLAN signal as well as normal distributed white Gaussian noise.
