摘要/Abstract

摘要：

随着卫星通信、移动通信、雷达侦察、电子战等无线通信领域的快速发展,MPSK和MQAM两类调制方式因具有较高的频谱利用率和良好的抗噪性能,得到了广泛应用。尤其是在星间链路通信中常用到BPSK、QPSK、UQPSK、64QAM等调制类型。文中在基于高阶累积量法的基础上,提出了新的基于特征参数提取的方法,实现了对BPSK、QPSK、UQPSK、64QAM调制类型自动识别技术。实验结果表明,该方法简单、有效、运算量小,且抗干扰能力强、识别率较高、实时性较好、适合工程应用

Abstract:

In recent years,with the rapid development of wireless communication field such as satellite communication,mobile communication,radar recognition,electronic war,MPSK and MQAM modulation modes have been widely applied,because of their high spectrum efficiency and good noise performance.BPSK,QPSK and UQPSK,64QAM are widely applied especially in the link communication between satellites.This paper puts forward an improved method of new characteristic parameters based on higher-order accumulation for automatic identification for BPSK,QPSK,UQPSK,64QAM signals.This method is simple and effective with small computational complexity,strong recognition ability,high recognition rate,and good real-time performance.

Key words: BPSK;QPSK;UQPSK;64QAM;link between satellites;identification of modulation type
