基于多值逻辑的双向工频自动通信系统

TWACS Based on Multi_Valued Logic

在以电力线为媒介的数据通讯中,双向工频自动通信系统由于具有独特的优点,通讯效果最好。但是它最大的缺点是通讯速率低。为此本文提出了用多值逻辑代替传统的二值逻辑以提高通讯速率。文中给出了多值逻辑条件下数据的调制解调原理和纠错原理,并推导出数字就错的最终求解公式。

Two way automatic communication system（TWACS） is the best way to communicate through power line. But the low communication rate becomes its marked shortcoming. In this paper, binary logic is replaced with multi-valued logic to increase communication rate. The principle of modulation, demodulation and data error correction based on multi-valued logic is given in the text. And the expression of data error correction is deduced.
