在数字通信领域中,HDB3码是一种非常适合在基带信号传输系统中传输的码型,并保持了 AMI 的优点.为了满足用户的需求,提高通信系统工作稳定性,HDB3编码器专用集成电路(ASIC)集成了插“V”、插“B”和“V”码极性纠正模块,通过仿真和硬件验证,它可以有效消除传输信号中的直流成分和很小的低频成分,可以实现基带信号在基带信道中直接传输与提取,同时能很好地提取定时信号.

In the field of digital communication,the HDB3 code is a code pattern,which is suitable for transmission in the the baseband signal transmission system and maintains the merits of AMI. In order to meet the needs of users and improve the working stability of communication systems,the inserting“V”module,inserting“B”module and“V”code polarity correction module were integrated in the application specific integrated circuit(ASIC)of HDB3 encoder. The simulation and hardware verifi?cation show that that it can eliminate the DC component and low?frequency component of transmission signals. Furthermore,the direct transmission and extraction of baseband signal can be realized in the baseband channel,and the timing signal can be ex?tracted well.
