| 摘 要： | 针对调制方式的盲识别,本文通过自回归模型提取特征参数,并采用k近邻法进行分类识别.仿真结果表明,这种方法可以在-1dB的极低信噪比条件下识别信号的调制方式,并且其性能受中心频率偏移和抽样频率变化的影响很小.

| Abstract: | To classify modulations blindly,this paper employs autoregressive models to generate feature parameters and the knearest-neighbour method to classify modulation types.Simulation results indicate that this method can classify modulations in a very low SNR environment such as -1dB,and be robust to the frequency offset and the dynamic change of sample frequency. |
