确定性信号是指可以用明确的数学关系或者图表描述的信号。若信号被表示为一确定的时间函数，对于指定的某一时刻，可以确定一相应的函数值，这种信号被称为确定性信号。
确定性信号的收敛速率慢于不相关信号的速率。
The convergence rate of deterministic signal is slower than the one of uncorrelated signal.
考虑到短波信道频率偏移的不确定性提出了相关搜索、FFT捕获的信号捕获方案。
Considering the uncertainty of frequency excursion, the scheme of signal capturing of correlate searching, FFT capturing is bring forward.
他将这种显现视为量子球模糊性或不确定性的信号，并认为这是在小尺度下发生分形行为的结果。
He describes this phenomenon as a signature of the fuzziness, or uncertainty, of the quantum sphere, and also as resulting from fractal behavior at small scales.
