摘　　要：数字传输分为基带传输和带通传输两大类。最佳传输系统定义为消除了码间干扰且抗噪性能最理想的系统,是数字通信原理教学中的重点、难点。基于LabVIEW软件仿真设计最佳基带传输系统和最佳带通传输系统,最佳基带传输系统中的脉冲成形滤波器和匹配滤波器通过公式节点编写实现;最佳带通传输系统中的脉冲成形滤波器和匹配滤波器调用LabVIEW自带的模块实现。实验结果表明,设计并实现的最佳基带传输系统和最佳带通传输系统性能良好,抗噪声能力强。基于LabVIEW的最佳传输系统设计不仅可以提高学生的学习兴趣,还有助于培养学生的工程实践能力和创新能力。Digital transmission is divided into baseband transmission and bandpass transmission.The optimum transmission system is defined as the system that eliminates intersymbol interference and has the optimum anti-noise performance.Aiming at the key and difficult problems in the teaching of digital communication principle,an optimum baseband transmission system and an optimum bandpass transmission system are designed based on LabVIEW.The pulse shaping filter and matched filter in the optimal baseband transmission system are realized by writing formula nodes.The pulse shaping filter and matched filter in the optimal band-pass transmission system are realized by calling the module of LabVIEW.The experimental results show that the optimum baseband transmission system and the optimum bandpass transmission system have good performance and strong anti-noise performance.The optimum transmission system design based on LabVIEW can not only improve students’learning interest,but also help to cultivate students’engineering practice ability and innovation ability.
