基于microchip公司的dspic33fj32mc204，在永磁同步电机上实现单电阻电流采样的foc控制源码，还有弱磁控制的哦。(Permanent magnet synchronous motor based on microchip company dspic33fj32mc204, single-resistor current the foc control sample source, the field weakening control.)

matlab程序，包括QPSK,16QAM,64QAM等多种调制方式的调制解调(modulation and demodulation of QPSK,16QAM and 64QAM etc.)

说明：  intelligent transportation system and internet of vehicles

本资源给出了用matlab画各种三维图的源代码，非常齐全。(The resorce provides the resorce programs of drawing 3D maps using matlab.)

说明：  程序功能：批量修改当前文件夹下文件的名称(Program function: batch modify the name of the file under the current folder)

说明：  经典无线链路预算模型，预测了在自由空间中由地形的非规则性造成的中值传输衰落。该模型适用于频段为20MHz至40GHz、路径长度为1km至2000km的情况。对于给定的传输路径，该计算机程序通过频率、路径长度、极化方向、天线高度、表面绕射率、地面有效半径和地面导电常数等参数可以确定传输损耗的大小。(Classic wireless link budget model, forecasts the in free space caused by terrain of regularity in the value decline.The model is suitable for the frequency of 20 MHZ to 40 GHZ, path length of 1 km to 2000 km.For a given transmission path, this a computer program can calculate the value of the transmission loss by frequency, path length, polarization direction, antenna height, surface diffraction, effective radius of the ground and ground conductivity constant parameters and so on.)

本程序适用于Gradient Magnitude Similarity Deviation: A Highly Efficient Perceptual Image Quality Index(this code is used for Gradient Magnitude Similarity Deviation: A Highly Efficient Perceptual Image Quality Index)

dsp28335开发板的AD采样程序，十分实用。(DSP28335 Development Board AD Sampling Program, Super Practical Dry Goods)

风力发电，发电机机侧变流器控制策略，希望能帮上忙(wind power，generator-side converter control strategy)

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)
