摘　　要：该方法将新的特征与传统参数进行全面融合,具有很高的正确识别率和良好的抗噪、抗干扰性能,并可成功区分二次调制信号和该频段内的FSK、PSK、QAM、噪声调频等其他干扰信号。新方法还通过并行处理思路提高了效率,减少了所需的信号样本点数,运算量较小,具有很强的工程实用价值。在实际的复杂环境中经过大量测试显示,新方法性能优越,其识别方法稍加改进也能扩展应用于其他环境通信信号识别,适用性强。The method in full combination of the new features with the traditional parameters, has high correct-recognition rate and good anti-noise and anti-interference performance, and can successfully distinguish the two-leveled multi-carrier signal from other interfering signals such as FSK, PSK, QAM and noise FM in this band. The new method can also improve efficiency via parallel processing ideas, reduce the number of required sigual samples, and with small amount of computation, is of strong engineering practical value. The extensive testing in practical and complex environment indicates that this method is excellent in performance. And the identification method, for its strong applicability and after slightly improved, may also be extended and applied to communication signal recognition of other environments.
