statistic noise

The statistic distribution expressions of target and noise in2-dimensions domain were established.

推导出了目标和噪声在二维投影空间中的分布公式。

Signal to noise ratio ( SNR) is required for maximum aposteriori probability ( MAP) decoder of Turbo codes, otherwise there is some loss of SNR. A new algorithm of SNR estimator is proposed, which is based on the high order statistic analysis.

Turbo码的MAP（最大后验概率）译码算法需要估值信噪比，否则会有一定的信噪比损失。

It is to make the time-correlation function a statistic to detect the target according to the different feature in time-correlation between signal and noise.

其基本思想是利用信号与噪声在时间相关性上的不同，构造时间相关函数作为一个统计量，进行目标检测。
