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.)
