| 摘 要： | 在简单介绍经典的频分制多路传输方案的基础上,着重讨论了采用频谱搬移法的多路传输方案。频谱搬移法不仅可以改善高通道的性能,而且还可以使电路结构模块化、标准化、系列化,因而具有较强的实用性。初步实验结果表明,本方案切实可行。

| Abstract: | A traditional Frequency-Divided Multiplex(FDM) system is first discussed.Then a new scheme of FDM system used frequency spectrum shift is introduced in detail.The new scheme can not only improve the performance of higher channels,but also make circuit modular,standard and series.So,it is of higher practicality.The experimental results show this scheme is practical. |
