This is a single sideband modulation source, for the signal and the signal has been modulated spectrum.
说明：这是单边带调制源码，求消息信号和已调信号的频谱。

The phase noise is usually specified, depending on the carrier offset, as a single-sideband phase noise referenced to the carrier offset.
相位噪声总是具体的， 取决于载波偏移， 作为相对于载波偏移的一个单边带噪声。

This paper discussed the double sideband noise figures and single side band noise figures of the superheterodyne receivers in a ideal hypothesis and the practical case respectively.
