通信原理综合性实验项目的设计与实践

Design and Practice of the Comprehensive Experiments in Communication Principle

本文在北京达盛公司研制的一套开放性软硬件相结合的TMS320VC5402实验平台基础上,以DSP为核心,结合外部相对独立的功能电路,给出了包含2FSK调制、2FSK非相干解调、巴克码帧同步、位同步等相关内容的2FSK传输系统综合性实验项目的设计实现,完善了实验教材中实验项目的知识结构,丰富了实验内容,加强了不同课程知识间的横向联系,为引导学生完成综合性、开放性和探索性的实验打下基础。

Based on an open TMS320VC5402 experimental platform developed by Beijing Dasheng company in which software and hardware are incorporated, this paper gives the design and implementation of comprehensive experiment for 2FSK transmission system including 2FSK modulation, 2FSK non - coherent demodulation, Bark code frame synchronization, bit - synchronization, and etc, perfects the knowledge structure of experimental items in experimental text - books, enriches experimental content, enhances parallel connection between different course knowledge, and does the spade work for leading students to finish open, comprehensive and exploratory experiment.
