Intensity Statistics of Random Signals in Gaussian Noise
摘要：
通过研究一个随机信号加一个随机相量和的模型，得到了高斯噪声下信号的强度统计特性。加性高斯噪声的信号强度的概率密度的贝塞尔变换的结果。强度统计的变换通常可以应用于独立随机信号的混合，其中之一是复值高斯随机过程。该方法用于从长时延高斯噪声中恢复微波脉冲传输的强度统计特性。
英文摘要：
The intensity statistics of signals in the presence of Gaussian noise is obtained by studying the model of a random signal plus a random phasor sum. The additive Gaussian noise is shown to result in a Bessel transform of the probability density of the signal intensity. The transformation of the intensity statistics can generally be applied to a mixture of independent random signals, one of which being a complex-valued Gaussian random process. It is used to retrieve intensity statistics of microwave pulsed transmission from Gaussian noise at long time delays.
