Description: 基于VHDL语言的HDB3码编译码器的设计
HDB3 码的全称是三阶高密度双极性码，它是数字基带传输中的一种重要码型，具有频谱中无直流分量、能量集中、提取位同步信息方便等优点。HDB3 码是在AMI码(极性交替转换码)的基础上发展起来的，解决了AMI码在连0码过多时同步提取困难的问题-Based on the VHDL language code HDB3 codecs design HDB3 code name is the third-order high-density bipolar code, it is the digital base-band transmission an important pattern, with no DC component spectrum, energy concentration, extraction bit synchronization information, such as the advantages of convenience. HDB3 code is in the AMI code (alternating polarity conversion code) developed on the basis of resolving the AMI code 0 yards too much even when difficult issues simultaneously extract Platform: |
