| Abstract: | 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. |
