此为事件触发型WSN（无线传感器网络）的密钥分发程序。 分为主程序KEYHANDOUT 5个可供加载到实际网络中的5个子程序PART1-5 还有一个初期密钥的建立KEYSOURCE函数。 调用时 1：先运行KEYSOURCE函数初始化环境。 2：在直接运行主函数KEYHANDOUT函数即可。 (Dies ist eine ereignisgesteuerte WSN (Wireless Sensor Networks) Schlüsselverteilungsprozess. Das Hauptprogramm ist in KEYHANDOUT geteilt 5 zum Laden in das eigentliche Netzwerk von fünf Unterprogramme zur Verfügung PART1-5 Es gibt auch eine Funktion der erste Schlüsselerstellung Hauptquellgruppen. Wenn Sie anrufen ein: zum ersten Mal ausgeführt Hauptquellgruppen Funktion initialisiert die Umwelt. 2: direkt ausführen, um die Hauptfunktion KEYHANDOUT Funktion.)

hamming编码的matlab小程序，要调用decode函数(a matlab program for hamming_code)

The signal received by a user over the forward link in such a high data rate system contains interference from the neighboring base stations. we note that the strength of this interference is a function of the network load in the neighboring cells. we obtain an expression for the received SINR (Signal to Interference and Noise Ratio) as a function of the traffic load in the interfering cells. Using this result, we propose an improvement to the SINR estimation scheme that is implemented in the current cellular data network. The proposed scheme provides a more accurate estimate of the user SINR by taking better account of the contribution of inter-cell interference. It builds on top of the current SINR measurement scheme by using a combination of pilot measurement and traffic load measurement

差分法比较曲线的形状相似度，接着筛选出有用曲线求相位差，给了原始数据，可以直接运行(Difference Method for curve shape similarity, then filter out the demand curve useful in phase, to the raw data, can run)
