摘　　要：MATLAB软件具有强大的仿真功能,是当今通信系统中一种重要的设计和仿真工具。本文在分析数字基带系统传输特性的基础上,运用MATLAB/Simulink动态仿真环境实现了双极性数字基带信号传输系统的建模和仿真,通过仿真眼图和误码率曲线对系统的抗噪声性能进行分析。实际仿真结果表明,该系统能够模拟双极性数字基带的传输过程,系统性能仿真分析的结果与理论基本一致,该系统达到设计的要求。The software MATLAB has powerful features. It is an important tool in communication system design and simulation. Based on the analysis of the digital baseband transmission characteristics of the system, this paper uses MATLAB/Simulink simulation environment to achieve the dynamic modeling and simulation of bipolar baseband signal transmission system. The anti-noise performance of the system is analyzed by simulation eye diagrams and bit error rate curves. The actual simulation results show that the system can process bipolar digital baseband analog transmission. The system simulation performance is consistent with the theoretical results. The system can meet the design requirements.
