Description: The first step to intelligent image/video processing for face recognition in uncontrolled scenery with complex backgrounds (outdoor environments, airports, train/bus stations) is face detection. The precision of the latter heavily depends your face recognition results. Typically scientists investigating in that field do not have the time or the ability to develop optimized C++ code ready for commercial use and confine themselves with the Matlab development process only. -The first step to intelligent image/video processing for face recognition in uncontrolled scenery with complex backgrounds (outdoor environments, airports, train/bus stations) is face detection.

Description: 还在为“基于MATLAB的OFDM系统仿真”的朋友，可以看看我总结的资料！
该代码通过综合了本站中的两个源代码，在MATLAB 7.0下完成OFDM系统的完美仿真：音频数据采集->S/P转换->16QAM映射->IFFT处理->添加CP->P/S->理想/多径信道传送->……（FFT等）->传输结果比较（前后频谱图、可以直接通过听前后的音频文件来辨别系统的好坏-理想信道时音质前后相同）。在此还要感谢那两位站员提供相关的代码，也希望能对其他人有帮助。更希望本站能吸引更多的编程爱好者再创佳绩。-KEYWORD:OFDM MATLAB 7.0 CP IFFT FFT P/S S/P
Also for the " Based on MATLAB simulation of the OFDM system," a friend, you can see my summary of the information! The code through a combination of the two site source code, MATLAB 7.0 at complete perfection OFDM system simulation: Audio Data Acquisition-> S/P conversion-> 16QAM mapping-> IFFT processing-> Add CP-> P/S-> ideal/multi-path channel transmission-> ... ... (FFT, etc.)-> transmission results (before and after the frequency spectrum can be directly before and after listening to audio files to identify the system good or bad- when the ideal channel before and after the same sound quality). This would also like to thank at the two stations to provide the relevant code, also hope to have helped others. I also hope to attract more site programming enthusiasts new heights.

Description: 一个cdma2000的系统仿真器，附英文手册-The cdma2000-UV Simulator estimates the performance of data transmissions at the physical layer
of the mobile communications technology cdma2000 1X. These wireless data transmissions enable
the communication between mobile stations (e.g., cellular phones, PDAs, laptops) and base
stations (i.e., the communication systems that provide network access to the final user). Examples
of these transmissions include voice, e-mails, and text messages. The simulation results are
calculated according to the simulation parameters set by the user. For example, the user may set a
non-moving mobile station in an indoor environment or a moving mobile station in a vehicular
environment. With the results obtained with the simulator, the user can perform different analyses
such as the degradation in system performance due to an increase of the number of mobile stations
or the effects of multipath channels on CDMA transmissions. Also, the cdma2000-UV Simulator
assists the user in understanding the

Description: An ad-hoc network with a sender, a destination and a third station act-
ing as a relay is analysed. The channels are modelled containing thermal
noise, Rayleigh fading and path loss. Di® erent combining methods and di-
versity protocols are compared. The amplify and forward protocol shows a
better performance than the decode and forward protocol, unless an error
correcting code is simulated. To combine the incoming signals the chan-
nel quality should be estimated as well as possible. Information about the
average quality shows nice bene¯ ts, and a rough approximation about the
variation of the channel quality increases the performance even more. What-
ever combination of diversity protocol and combining method is used second
level diversity is observed. The relative distances between the relay and the
stations has a large e® ect on the performance.

Description: 首先实现一个ant蚂蚁类，用此蚂蚁类实现搜索。
算法按照tsp问题去解决，但是在最后计算路径的时候有区别。
比如有10个城市,城市1是配送站，蚂蚁搜索的得到的路径是1,3,5,9,4,10,2,6,8,7。
计算路径的时候把城市依次放入派送线路中,
每放入一个城市前，检查该城市放入后是否会超过车辆最大载重
如果没有超过就放入
如果超过，就重新开始一条派送路线
……
直到最后一个城市放完
就会得到多条派送路线
这样处理比较简单可以把vrp问题转为tsp问题求解
但是实际效果还需要验证。(First of all, a ant ant class is implemented, and the ant class is used to search.
The algorithm is solved according to the TSP problem, but there is a difference in the final calculation of the path.
For example, there are 10 cities, and 1 of cities are distribution stations. The path for ants to search is 1,3,5,9,4,10,2,6,8,7.
When calculating the path, place the city in the delivery route,
Before entering a city, check whether the city will exceed the maximum load of the vehicle after it is put in
If it's not over, put it in
If it's over, start a delivery route again
......
Until the last city is over
You'll get multiple delivery routes
This approach is relatively simple, you can change the VRP Problem to TSP problem solving
But the actual results need to be verified.)

In such a system, customers arrive at the system in the rear row into a queue, then receive service at the idle service desk, while the service time of each service station obeys the negative exponential distribution of the same parameter. After the service is finished, the customer automatically goes away.)
