卫星通信中数字调相信号调制方式识别方法研究
针对数字卫星常用的 7 种通信信号调制方式(QPSK、8PSK、16QAM、32QAM、64QAM、16APSK、32APSK)，对零中心归一化瞬时幅度谱密度最大值、四次方谱、幅度、高阶累积量四种特征参数进行了分析，提出了一种联合特征参数的信号调制识别方法．(Aiming at seven communication signal modulation modes commonly used in digital satellite (QPSK, 8PSK, 16QAM, 32QAM, 64QAM, 16APSK and 32APSK), four characteristic parameters of zero-center normalized instantaneous amplitude spectral density, quadratic spectrum, amplitude and high-order cumulant are analyzed, and a signal modulation recognition method of joint characteristic parameters is proposed. Method.)

共振解调技术是经过包络分析将淹没在背景噪声中的微弱信号提取出来，然后输出一个消除了振动信号干扰的信号，接着对该信号进行频谱分析，并且通过利用滚动轴承的故障特征频率进行分析，共振解调法是目前应用于实际的常用方法。(The resonance demodulation technique is to extract the faint signal submerged in the background noise by envelope analysis, and then output a signal that eliminates the interference of the vibration signal. Then the signal is analyzed and analyzed by the frequency of the fault characteristic of the rolling bearing. The resonance demodulation method is applied to the actual situation at present. The commonly used methods.)
