摘　　要：结合通信信号源的相关原理和技术,提出了一个采用MATLAB程序设计语言完成的多功能通信信号源仿真系统。该系统能够产生模拟调制信号AM、DSB、SSB,数字载波传输调制信号ASK、FSK、PSK、QAM、MSK、GMSK等基本的通信信号,并能设置信号的特征参数,以及进行相应的时域和频域分析。亦从宏观上介绍了此通信信号源的整体结构,给出了它的功能分析和实际应用。We summarize the simulation techniques, and then present a multifunctional communication signal source system hy using the programming language MATLAB. This system is used to generate analog modulation signals such as AM, DSB, SSB, digital signals transferred by carrier wave such as ASK, FSK, PSK, QAM, MSK, GMSK, and other basic communication signals. The system can also set characteristic parameters of signals, analyze time domain and frequency domain, and generate spectrum. Finally, the unitized structure of this cornrnunication signal source is presented, the function is analyzed, and the practice applications are shown.
