这个问题来自平稳随机序列的相关函数。
This problem arises from the correlation functions of stationary stochastic sequences.
文中利用对称相关函数理论，分析了抵消平稳随机过程中与信号不相关的加性随机噪声的机理，并应用于线谱信号检测。
The theory of symmetrical function is used to suppress additive stationary random noise; assumption is that the signal and the noise are mutually uncorrelated.
假设输入函数为各态历经的平稳随机过程，得出各输出响应的谱密度与频率的关系。
The relations between spectrum densities of system output responses and frequency were obtained by assuming input functions to be ergodic and stable stochastic processes.
