现代通信系统第二版 的整个书得源代码，很全的代码，希望对同学有帮助(The second edition of modern communication systems have the source code throughout the book)

信号由三个频率分别为0.01，0.1，0.2的正弦信号组成。 (1)作信号的连续小波变换。 (2)自己选择小波基数，对信号进行多尺度分解，将每一个正弦信号分开。 (3)重建原信号。 (Signal from the three frequencies were 0.01,0.1,0.2 sinusoidal signals. (1) continuous wavelet transform for signal. (2) choose the wavelet base, multi-scale decomposition of signals, a sinusoidal signal of each separate. (3) reconstruction of the original signal.)

说明：  这是一个利用FFT内插法求解载波频率问题，精确度很高。(This is to solve a carrier frequency problems using interpolation FFT.It is high degree of precision.)

说明：  该文件包括了连续周期信号的单边带及双边带频谱分析的所有源代码及仿真波形，设计完整，而且符合要求。(The document includes a continuous cycle, and bilateral single-sideband signal with a spectral analysis of all source code and simulation waveforms, design integrity, but also meet the requirement.)

说明：  协调控制算法，基于发电厂锅炉与汽轮机模型，首先将模型离散化，然后实施控制算法(Coordinated control algorithm, based on power plant boiler and steam turbine model, discrete model first and then the implementation of control algorithms)

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 (Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures, intermediate design and interpolation and decimation filter design. The filter design is using the window function method, according to the requirements of the design of window function, get the length of the window function. Then the interpolation, filtering, extraction, and finally obtain the variable wave file, sampling after the addition of contrast and polyphase decomposition results of two methods for convolution last direct convolution.)
