Description: 本课程设计完成了基带线路码产生电路的设计，数字基带信号的传输是数字通信系统的重要组成部分之一。在数字通信中，有些场合可不经过载波调制和解调过程，而对基带信号进行直接传输。为使基带信号能适合在基带信道中传输，通常要经过基带信号变换，这种变换过程事实上就是编码过程。本些课题实现了这样的编码过程。-This course is designed to use VHDL hardware description language completed the base-band circuits have a code of the circuit design. Digital base-band signal transmission of digital communications systems is an important part of one.In the signal before transmission to go through the code to deal with. In digital communications, there are some occasions, not through the process of modulation and demodulation, and base-band signal for direct transmission. In order to be able to base-band signal for the base-band transmission channels, usually after a base-band signal transformation, the transformation process is in fact the process of encoding.
