Combination of MATLAB and sound card to realize Gaussian sine wave for decoding Morse code

Abstract

To actualize Morse code used for wireless communication simulation and to produce Gaussian sine signals, the method of combine Matlab and integrated sound card can be used to design, generate and realize the Gaussian sine wave. The paper is based on the principles of all sorts of virtual signal and design process of Matlab and provides the operation procedure and grammatical form of Matlab. Eventually generated the Gaussian sine signal of center frequency for 60 KHz, bandwidth for 50 MHz and sampling frequency for 60%.
