Research and Analysis of Digital Baseband Transmission System Based on MATLAB
Journal Title: Journal of Secure Communication and System - Year 2017, Vol 1, Issue 1
Abstract
This paper mainly studies the basic concept of baseband transmission of digital signal and the transmission process of digital signal baseband transmission and how to design digital baseband transmission system with MATLAB software simulation. This paper fi rst introduces the theoretical basis of this subject, including digital communication, the composition of digital baseband transmission system and digital baseband signal transmission process. Then the paper introduced the characteristics of digital baseband transmission system, including digital PAM signal power density and common line pattern, and by comparing choosing the fi nal bipolar zero return code. Then we introduced the MATLAB simulation software. The conditions of the best reception of the digital baseband signal are described and how the waveform of the baseband signal is observed by an oscilloscope. Finally, according to the basic steps of simulation process, the simulation process of digital baseband transmission system is realized by MATLAB simulation tool, and the system is analyzed.
