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.

正交频分复用 （OFDM） 是一种通信技术，通信信道分为同样间隔的频段的数目。副载波携带用户信息的一部分是在每个波段中传输。每个子载波与每一个其他副载波，从常用的频分复用 （FDM） 鉴别 OFDM 是正交 （相互独立）。频分复用 （FDM） 是一种技术，通过单一的传输路径如电缆调制解调器或无线系统同时传输多个信号。每个信号传播在其自身独特的频率范围内 （载波） 调制的数据 （文本、 语音、 视频等）。正交 FDM （OFDM） 扩频技术将数据分布在一大批以精确的频率间隔的载体。这种技术中的这个间距提供"正交"以防止解调器看到自己以外的其他频率。
