6、DL语言27武汉理工大学《通信原理》课程设计说明书Abstract In the digital baseband signal transmission, HDB3 code (the third order high density bipolar codes) is one of the commonly used transmission type. This design aiming at the characteristics of HDB3 code in digital baseband transmission sy
7、stem, the encoder is divided into three parts: V module, interpolation module B, single polarity dual polarity change module to realize the HBD3 code output. In the process of coding, the main shift register and the counter is used to realize the whole process of plug V
8、plug B, and the introduction of the bipolar codes for accurate identification of "V", "B", "+ 1", "V",
