一篇非常有参考价值的英文文献，适合做认知无线电方面研究的人员阅读。(A very valuable reference in English literature, suitable for cognitive radio in the study who read.)

在阅读过2005年的HOG论文后写的梯度方向直方图的代码(I wrote the code of HOG after I read the paper which name was Histograms of Oriented Gradients published at CPRV05.)

图像特征提取 特征提取 matlab 特征提取 图像特征 (Image feature extraction feature extraction feature extraction matlab image features)

说明：  matlab科学计算继续上传，一共10个章节，由浅入深，几乎包括了绝大部分的科学计算方法以及仿真。本人把部分算法做了优化，更为完善(matlab scientific computing continue to upload, a total 10 chapters, easy-to-digest, almost, including most of the scientific method of calculation and simulation. I have done a part of algorithm optimization, a more perfect)

spatial filter for spatial domain filtering

上传一个多输入多输出的状态空间方程的预测控制程序，采样三输入双输出。仿真结果能得到期望的设定值.(Upload predictive control program a multi-input multi-output state space equations, three-input dual-output sampling. The simulation results can be obtained the desired setpoint.)

OFDM传输技术的原理和matlab仿真(OFDM transmission technology and the principle of matlab simulation)

main_IS95_forward.m 此函数用于IS-95前向链路系统的仿真，包括卷积编译码、扩频调制，匹配滤波，RAKE接收等相关通信模块。 仿真环境: 加性高斯白噪声信道. 数据速率 = 9600 KBps (main_IS95_forward.m This function is used to forward link IS-95 system simulation, including the convolution encoding and decoding, spread spectrum modulation, matched filter, RAKE receiver, and other related communication module. Simulation environment: additive white Gaussian noise channel. Data rate = 9600 KBps)

本例用matlab语言实现了8dpsk的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。(cases using the Matlab language of the codec 8dpsk and awgn channel through the simulation. Using Monte Carlo simulation, to be error performance, drawing curves. Algorithms can be used to study or courses.)
