Deep Supervised Hashing for Fast Image Retrieval

VC写GPS简单源码，易上手，适合初学者学习，请指教(GPS VC write simple source, Yishangshou, for beginners learning, improve!)

1. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请清楚的描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用S-function产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。 (Doppler spectrum of radio channel 1, please answer the following questions (1) In some wireless channel, radio channel Doppler shift will cause the output signal aliasing. Please clearly describe aliasing for various reasons )

OFDM的QPSK及其调制matlab程序(OFDM-QPSK modulation matlab and its procedures)

说明：  这是一个用c#实现的GPS定位系统软件，你只需输入所要查询的城市名就会连接到地图，你可以对其执行放大，缩小，左移，右移，上移，下移等操作，非常实用，绝对值得，希望对您有帮助 (A software about the GPS positioning system.You can search for a city which is linked to the map,just by inputting the name,and also you could make it bigger,smaller,move left,right,up and down.You won t miss it.)

说明：  实现turbo码编程，是matlab源程序。(matlab program of turbocoder)

Clustering analysis based on Euclidean distance, BP neural network function fitting and pattern recognition, A noise auxiliary data analysis method.

说明：  用Gardner算法时钟同步的BPSK的源程序(Gardner algorithm for clock synchronization with the source code BPSK)

说明：  通信天线建模与MATLAB仿真分析书中10-4题目代码(Lossy Extractio Communication Antenna Modeling and MATLAB Simulation Analysis Book 10-4 Topic Code)
