    压缩包有六个文件，分别是绘制圆波导TE波和TM波各模式的横截面场分布、三维静态场分布、三维动态演示。能够绘制的模式有TE波或TM波01-23共2*9种。除截面场分布文件是运行程序后自动生成9种模式分布图外，其余文件是运行后根据提示输入参数（如绘TE11就找到对应的文件，由提示输入1，1即可），参数是模式下标。圆波导模多存在极化兼并，图中可以看出，但是只绘制了余弦情况下对应的场分布（正弦只是旋转了90度）。压缩包里有程序运行的部分结果。时间仓促，结果没来得及仔细核对，有错误希望指出。

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.
