为系统辨识，神经网络初学者提供一种简单的程序设计方法，希望大家多多共享，互利互惠。(In order to identify the system, the beginners of the neural network provide a simple method of programming. We hope that all of us can share more, mutual benefit and mutual benefit.)

实现了省份和城市的二级级联效果，简单易懂，大家可以参考(It achieves the secondary cascade effect of provinces and cities, which is simple and easy to understand. You can refer to it.)

通过将待进行计算的向量放入二维数组中，然后编程实现皮尔森和余弦相似度公式，计算向量之间的相似度。(caculate the similarity of vector)

VB抓图小精灵，在桌面区截图的时候，请按左上到右下的方向选择屏幕区域！活动窗口抓图的时候，请在2秒钟内选择好活动窗口！整个桌面抓屏则直接捕获整个桌面。所显示的缩略图会在视觉上失真，但不影响真实保存的图形内容！

随着价格降低，STM32变得越来越流行了，这是入门STM32的好资料。(With the cost going down, STM32 is becoming more and more popular. This is a good document for those who want to study STM32.)

WLAN仿真－发送机 wlan No Comments 设置完系统参数后，开始产生发送数据。 1. 产生随机的发送bit（tx_bits），这里不考虑信道编码。 2. QAM映射 3. 将数据映射到不同载波，形成OFDM符号 4. 产生pilot，并将pilot插入OFDM符号中 5. 加入dc和guard子载波 6. 进行ifft，将频域信号变到时域，并加入循环前缀 7. 对信号进行overlap window 8. 在时域产生short preamble 9. 在时域产生long preamble 10. 将preamble和数据符号组成packet 11. 升采样 得到信道传输的数据Tx_signal_up 具体程序见附件 wlan_transmitter.m-WLAN Simulation- wlan No Comments transmitter system parameters set finished, the beginning to have to send data. 1. Have sent random bit (tx_bits), here does not consider channel coding. 2. QAM mapping 3. The data is mapped to a different carrier to form OFDM symbols 4. Have a pilot, and pilot inserted OFDM symbols 5. Adding dc and guard subcarriers 6. To carry out ifft, will change the frequency domain signal to time domain, and add cyclic prefix 7. the signals overlap window8. In the time domain have a short preamble9. In the time domain have a long preamble10. the preamble and data symbols packet11. or sampling re
