matlab 中的LOMB功能程序包 help中找不到这个程序包，问同学要到的 希望对大家有所帮助(matlab LOMB function can not be found in the package help this package, asked the students to want to help everyone)

MATLAB Image Detection

超宽带定位系统，较好的一本书，涉及很多方面的内容(Ultra-wideband positioning system, a good book, involving many aspects)

著名芯片74LV245芯片数据使用手册，讲解很全面(Well-known chip-chip data 74LV245 manual to explain the very comprehensive)

产生一个典型的LFM波形，包括包括其时域波形（实部、虚部）和频谱。(Produces a typical LFM waveform, including including the (real part, imaginary part) and a spectrum of the time domain waveform.)

该程序是软件无线电中信道化技术的仿真历程，使用了“多相滤波结构”，将32个频率分量进行调制，平均调制在频谱之中，提升了发射信号的频谱利用率。该程序有利于对信道化与多相滤波的理解。(This program is the simulation process of channelization technology in software radio. It uses a "polyphase filter structure" to modulate 32 frequency components. The average modulation is in the spectrum, which improves the spectrum utilization of the transmitted signal. The program is helpful for understanding channelization and polyphase filtering.)

图论的入门课件，很好的~特意拿出来share~(a very good sorce about grap theory intrduction.)
