摘要
针对PSK和QAM这两种数字调制信号,提出了联合利用信号包络归一化方差、幅度统计矩、瞬时参量峰度的自动识别算法。仿真表明在较低信噪比下可达到很高的识别率。
The paper integrates variance to the square of the envelope normalization, amplitude statistical and kurtosis of the instantaneous parameter to recognize MPSK and MQAM. The computer results show that the algorithm is very effective under low SNR conditions.
