中文摘要:
      首先叙述了调制识别技术在通信对抗中的研究意义、单载波与多载波调制的通信调制系统和灵巧通信对抗,然后介绍了无线数字信号的调制样式识别的研究现状。为了能够为灵巧通信对抗打下良好的基础,很好地实现单载波与多载波调制系统中信号特征的类间、类内识别是十分重要的。提出了一种用于识别串行单载波和并行多载波的调制样式识别算法,此算法能够对快变瑞利信道下完成MPSK和OFDM的调制样式识别。仿真结果表明,在信噪比为7 dB时,识别正确率可以达到90%以上。
英文摘要:
      Firstly, this paper describes the significance of research on modulation identification techniques in communication countermeasure, the single carrier and multicarrier communication modulation system, the smart communication countermeasure. Then, it introduces the actuality of research on modulation identification about wireless digital communication. For making a good foundation for the smart communication, it is very necessary to realize the signal features’ inter class and intra class identification well in the single carrier and multicarrier modulation system. This paper proposes a new algorithm for modulation identification about the single carrier and multicarrier. The algorithm is able to complete the signal features’ modulation identification over the time varying Rayleigh channel between OFDM and MPSK. Simulation results demonstrate an over 90% correct classification rate could be reached when the SNR is above 7dB.
