数字基带通信系统的设计，实现了AMI、HDB3、和CMI码的变换和反变换。包含了PCM编解码的部分。-Digital baseband communication system design, implementation of AMI, HDB3, and CMI code transform and inverse transform. Contains part of the PCM codec.

基于FPGA的CMI的编码与译码，且可以正确运行。我自己写的。-FPGA-based CMI encoding and decoding, and can be run properly.
