A special four order cumulant was defined to extract DOAs and Doppler frequencies from additive Gaussian colored noise.

The new method puts emphases on dealing with all kinds of noise from the imaging process, and USES Gaussian distribution to blur parameters of straight lines in order to ensure extraction robustness.

算法重点考虑到成像过程中必然引入的各种噪声，用高斯分布函数模糊化直线参数，使提取具有良好的稳健性。

In order to estimate the spectrum of the signal from the observed data with additive noise, the prior Knowledge of the noise is always used.

为了从有附加噪声的观测数据中估计信号的谱，噪声的先验知识总是要应用的。

Most recently, a team from Stanford took the helm of Sequoia to run computational fluid dynamics simulations -- a process that requires a finely tuned balance of computation, memory and communication components -- in order to better understand engine noise from supersonic jets.
