| 摘 要： | 码间串扰和信道噪声是影响基带传输系统性能的两个主要因素。因此，如何消除它们的影响，使系统的误码率达到规定的要求是数字基带系统中必须研究的两个问题。奈奎斯特第一准则为消除码间串扰奠定了理论基础。本文将以此为依据，通过使用Systemview和MATLAB软件实现对基带传输系统的仿真，并根据所得图形从消除码间串扰的角度来定性地分析无码间串扰系统函数的传输特性。实验中所得结果将对我们的理解和实践均有一定的指导作用。

| Abstract: | Intersymbol interference and channel noise are the two main factors to influence base-band transmission system performance.Therefore,reducing the impact of these two factors and making the bit error rate suitable for the real requirements are two issues that must be studied in digital base-band system.The first Nyquist criteria for the elimination of intersymbol interfrence lays a theoretical foundation,which is the basis of this paper.Through the analysis of performance obtained by the Systemview and MATLA... |
