内容是关于 两个单片机之间的通信.一个做主机,另一个做从机.从机负责显示液晶显示(LCD1602)时钟(DS12887).通过上位机指令控制,并调整时间.并且控制闹钟的时间

ns2 是一款用于仿真网络的软件 该源码包含了 书中的所有源代码-ns2 is a soft which can be used to simulate network,

算法P&O如图1所示，电路如图2所示。我建议使用带3.3V电源的轨对轨放大器，以获得最佳效果并保护ADC。TI的OPA2350是一个不错的选择。每0.5秒跟踪一次最大功率点。

使用softAP实现多方聊天通讯的例子源码，首先把多部手机连接到一个局域网中，在一个手机上安装服务端，然后服务端会自动显示一个可访问的IP地址并等待客户端连接，在其他手机上安装客户端，输入服务端显示的IP地址点击连接就可以与服务端进行连接，不需要改动源码里面的任何东西，亲测有效。

OFDM Rayleigh simulation

现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.
