Design of a Digital Baseband Transmission Signal Coding Software Based on Java

Aiming at the lack of visual interface in digital baseband signal coding system, this paper designs a coding software for digital baseband transmission signal based on Java. Firstly, the common pattern of baseband transmission and its coding principle are given. Then the software interface is designed by Java Swing, and the algorithm of common coding is given at the same time. By giving the original message code, the AMI, HDB3 and other coding results can be obtained. The experimental results show that the software can perform digital baseband coding on the message code.
