基于EDA技术的HDB3编码器的设计与实现

Design and Implementation of HDB3 coder Based on EDA

HDB3码是数字基带通信系统中重要组成部分之一,因其具有无直流成份,检错能力强,具有时钟恢复性能等优点,成为ITU推荐使用的基带传输码型之一。首先介绍了HDB3编码的原理和方法,提出了一种基于EDA技术实现的HDB3编码器的方法,具有电路简单,成本低,开发周期短,执行速度高,升级方便等特点。

HDB3 is an important part in the digital baseband signal transmission, which became a code type recommended by ITU because of the advantage of zero DC component, great error detection, clock scavenge capability etc. The principle of HOB3 code is introduced first in this paper, and then a HOB3 encoding system which is designed based on electronic design automatic technique was supplied, the advantages include simple circuit, low cost, short development cycle, high speed performing, expedience of updating etc.
