自己做的积分电路模块，很好的东西哟！！！！！！！！！！！！！(Own integral circuit module, a very good thing yo! ! ! ! ! ! ! ! ! ! ! ! !)

利用BLACKMANHARRIS窗口设计一个频率采样型FIR滤波器，对一段含噪音的音乐信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。(design a frequency-sampling FIR filter utilizing BLACKMANHARRIS window to filter and de-noise some of the music signal,and analysis filtering performance based on waveform and spectral before and after filtering.)

Since the first edition of this book was published seven years ago, the field of modeling and simulation of communication systems has grown and matured in many ways, and the use of simulation as a day-to-day tool is now even more common practice. With the current interest in digital mobile communications, a primary area of application of modeling and simulation is now in wireless systems of a different flavor from the `traditional ones. This second edition represents a substantial revision of the first, partly to accommodate the new applications that have arisen. New chapters include material on modeling and simulation of nonlinear systems, with a complementary section on related measurement techniques, channel modeling and three new case studies a consolidated set of problems is provided at the end of the book.

对数字信号的波形及其频谱分析，着重比较其在时域和频域上的差别(Digital signal waveform and its spectrum analysis, focused on comparative differences in the time domain and frequency domain)

MATLAB实现快速正交变换，与传统的FFT算法相比拥有更高的分辨率，但是运算时间较大， 在目标检测、频率分析、降噪方面都有着广泛的应用(MATLAB to achieved FOS_convert, compared with the traditional FFT algorithm has a higher resolution, but the computation time is large, the target detection, frequency analysis, noise reduction have a wide range of applications)
