检测双边带信号通过窄带FBG滤波后，成为单边带信号的光谱图，结果基本符合分析预期。

Since results in line with expectations, it preliminarily prove that use of narrow-band FBG to realize SSB in RoF can inhibiting decay caused by dispersion better.

分别讨论了在理想假设和实际情况下超外差接收机的双边带噪声系数和单边带噪声系数，给出了单边带接收机的某些设计方案。

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.

振幅调制分为4种方式：AM(普通调幅)、DSB(抑制载波双边带调幅)、SSB(单边带调幅)、VSB(残留边带调幅)。

Amplitude modulation is divided into 4 ways: am (amplitude), DSB (bilateral with carrier suppression modulation), SSB (single sideband modulation), VSB (VSB).
