A linear method for data classification

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based simulation design MIMO_OFDM communication systems. This system includes a QPSK modulation and demodulation demodulation, IFFT modulation, space-time coding and decoding, channel estimation based training symbol communication module.)

永磁同步电机的直接转矩控制，自己搭建的仿真模型，基于Simulink仿真系统。(Direct torque control of permanent magnet synchronous motor, build their own simulation model, based on Simulink simulation system.)

matlab code for beging cc motor...

说明：  AD835的仿真模型,用matlab的工具箱，simulink搭建的(AD835 simulation model, using matlab toolbox, simulink built)

关于天线理论的一本书，对散射的研究很深刻，适合作为隐身设计的参考资料(A book about the antenna theory, the research on scattering is very deep, suitable as a stealth design reference)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)

这个程序可以用来计算复杂网络中的介数，稍微修改就可以实现边介数和点介数的计算。(This program can be used to calculate the number of referrals of complex networks, a slight modification can calculate the number of edges and points referral referral number.)
