【正文】 西北工業(yè)大學明德學院本科畢業(yè)設計論文2 3AbstractIn this paper, we first introduce the history and development of munication, then introduces the digital signal of binary and Mary the carrier amplitude, frequency, or phase modulation, and amplitude shift control (ask) for example to use the integrated environment of MATLAB Simulink simulation platform of modulation and demodulation principle, process and characteristics of the deep understanding and various modulation performance simulation. For different modulation and demodulation, let them under Gaussian white noise or random environment, their signal to noise ratio, gain and bit error rate (BER) are pared and analyzed, summed up their respective advantages and disadvantages as well as application.Keywords: binary, multi band, MATLAB, Simulink, Gauss white noise 西北工業(yè)大學明德學院本科畢業(yè)設計論文4前言 當今時代是信息化時代，而信息的數(shù)字化也越來越為研究人員所重視。關鍵字：二進制，多進制，MATLAB，Simulink，高斯白噪聲西北工業(yè)大學明德學院本科畢業(yè)設計論文ABSTRACTIn this paper, we first introduce the history and development of munication, then introduces the digital signal of binary and Mary the carrier amplitude, frequency, or phase modulation, and amplitude shift control (ask) for example to use the integrated environment of MATLAB Simulink simulation platform of modulation and demodulation principle, process and characteristics of the deep understanding and various modulation performance simulation.
