学习matlab 小波工具箱的好资料 大家共同进步(Study of the matlab wavelet toolbox common good information on the progress of U.S.)

说明：  FSK差分检波系统仿真的课程设计 本课程设计主要利用MATLAB集成环境下的Simulink仿真平台，设计一个FSK信号差分检波系统。观察FSK调制前后的信号波形,并对调制前后信号的频谱进行分析,再以调制信号为输入，构建差分检波解调系统电路，观察解调前后的信号波形，并对解调前后信号的频谱进行分析。加入噪声分析通过三种不同信道FSK信号差分检波系统接受信号的性能。仿真结果，基本达到课程设计要求。(FSK differential detection system simulation of the curriculum design of this course the main use of MATLAB integrated design environment of Simulink simulation platform, the design of a FSK signal differential detection system. Observed before and after FSK modulation signal waveforms, and modulation signal spectrum before and after analysis, and then modulated signal as input, build a system of differential detection demodulator circuits, observe the pre-and post-demodulation signal waveforms, and signal demodulation spectrum before and after analysis. Adding noise analysis through the three different channel FSK signal differential signal detection system to accept performance. The simulation results, the basic courses to meet the design requirements.)
