In the modulation of amplitude, there are ordinary amplitude modulation ( the standard amplitude modulation AM), restraint signal carrier Double Side Band ( DSB) and restraint carrier Single Side Band ( SSB) according to the numbers of frequency spectra of the selected modulated signals. 在幅度调制中,根据已调信号的频谱分量不同,分为普通调幅(标准调幅AM)、抑制载波的双边带调幅(DSB)、抑制载波的单边带调幅(SSB)等。
Topological relationship replaces distance band to define layer sets, and a single side active set is proposed to improve efficiency and robustness. 提出用拓扑关系代替距离值范围定义各层体素集,并通过单侧活动集定义使算法更为高效和鲁棒。
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. It also gave some considerations designing the single side band receiver. 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。
