single-tone Frequency-Modulated wave 单音调制FM波
single-frequency continuous wave 单频连续波
This paper proclaims similarity of distribution between light strength of monochromic Fraunhofer's single - slit diffraction and square - wave frequency spectrum.
本文揭示了单色光夫琅和费单缝衍射的光强分布与矩形波频谱分布之间的相似性。
The most major advantage of the method lies in the fact that only the interference wave with single frequency can be suppressed, and the loss of useful signal is very limited.
本方法的最大优点是仅对单频干扰波进行有效的压制，对有效波的损失很小。
Next, minimum mean square error (MMSE) filters are applied to the received signal to recover single user signal wave thus implementing user separation and frequency synchronization at the same time.
然后，对接收到的信号应用最小均方误差滤波恢复单用户信号波形，从而同时实现了多用户信号分离及频率同步；
