摘要
数字基带传输具有非常重要的研究及应用的的意义,而码间干扰是一种常见现象,它对该系统具有很大的影响,因此研究码间干扰非常重要。首先通过Matlab搭建数字基带传输系统,然后通过噪声和码元速率与系统带宽不匹配来引入码间干扰,最后对这两种方法引起的码间干扰进行了研究和仿真分析。
Digital baseband transmission is of great importance to the research and application,and ISI is a kind of common phenomenon,it has a lot of influence to the system,so the study on ISI is very important.Firstly,digital baseband transmission system is set up by Matlab,then ISI is introduced by the noise and code element rate without matching the system band.Finally,ISI by these methods causing is re searched and simulated.
