基于扩频Modem及低压电力线路的分组数据传输技术

The Packet Data Transport on the Low Voltage power Lines Based on the Spread Spectrum Modem

为了充分利用低压电力线资源，就 Ｘ．２５ 数据终端设备（ Ｄ Ｔ Ｅ） 的接入问题，提出一种用电力线作传输线的方法。主要介绍了电力线的信道模型、扩频调制解调器（ Ｓ Ｓ Ｍｏｄｅ ｍ）

Aimed at the connection of X.25 DTE to public data networks, we introduce a approach for transporting packet data in order to reuse the low voltage power lines. The channel model of power lines, the structure of SS modem, and the practical access scheme of X..25 DTE are also presented in this paper.
