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.

这是一个使用UDP协议通信的例子程序，非常简单，没有做错误处理机制。由于UDP本身是无连接、不可靠的通信协议。会因为不同的网络环境，有可能会产生数据丢失、数据重复、顺序错乱等情况。 　　示例程序包含一个服务器端和一个客户端，可以多个客户端接入服务器端。-This is an agreement to use UDP communication examples procedures, is very simple, not so error-handling mechanism. Because UDP is a connectionless, unreliable communication protocol. Because of different network environment, there may be data loss, data duplication, the order of disorder and so on. Examples of the procedure includes a server-side and a client, multiple clients can access server-side.
