摘要

利用幂级数和统计理论分析了CDMA信号的频谱再生和信道内失真导致的增益压缩或扩展。所提出的CDMA信号时域模型比广泛使用的窄带高斯噪声假设能给出更精确的失真估计。该模型还用于显示CDMA信号与高斯噪声统计特性的差异。

Accurate prediction of spectral regrowth and in-channel distortion based on CDMA signal time-domain model

Spectral regrowth of a CDMA signal and in-channel distortion causing the gain compression or expansion are analyzed using the power series and statistical theory. The proposed time-domain model of the CDMA signal is shown to give more accurate distortion estimates than the widely used narrow-band Gaussian noise assumption. The model was also used to show the difference between statistical properties of the CDMA signal and the Gaussian noise.
