本科生毕业论文 （设计） 题目：基于MATLAB的最佳基带传输系统分析 学 院 机电工程学院 专业班 电子信息工程07 2班 学生姓名 指导教师 撰写日期：2011年 4 月 19 日 摘 要 20世纪60年代出现了数字传输技术，它采用了数字信号来传递信息，从此通信进 入了数字化时代。数字通信系统主要的两种通信模式 :数字频带传输通信系统，数字基 带传输通信系统。本文主要研究通信系统中的关键技术－数字基带传输，基带系统在数 字通信中有重要的代表性。主要包括基带系统的结构、传输的方式及无码间干扰条件的 特性研究。在综合考虑信道的加性噪声干扰及限带信道会引起码间干扰的这两方面因 素，并研究其最佳基带传输的发送及接收滤波的设计问题。本文还着重的研究基于 MATLAB语言的数字基带传输特性，通过MATLAB设计并仿真基带系统，在比较实测系统 与理论研究的基础上加深了对基带传输特性的理解。 关键词：数字基带传输，码间干扰，时域均衡 Based on MATLAB the best base-band transmission system analysis Abstract 20 emerged in the 1960s digital transmission technology, its adoption of a digital signal to transmit information, from communications to enter the digital era. Digital Communication System's two dominant mode of communication: digital transmission bandwidth communications systems, digital base-band transmission communications systems .The text introduces mostly about key technology of correspondence system which is numeric base-band transmission ，it is an important representative. The base-band transmission ， includes structure of the correspondence system and its transmit manner and the condition of without Inter-code interference. Channel considered in the increase of noise interference, and with limited channel will cause interference between the two yards factors, and study their best base-band transmission sending and receiving the design of the filter. In following ，the text emphasize studies numeric base-band transmission base-on MATLAB language and we use it to design and imitate base-band system. ，we compare true-test system with theoretic system，so we get more understanding in the field of base-band transmission. Keywords ：digital base-band;code of interference;time domain balanced
