摘要
为了提高MPSK与MFSK信号的类间识别率,通过对选取尺度因子的研究,提出了一种最佳尺度因子的选取方法,对MPSK与MFSK信号的类间识别器进行了改进.最后进行了计算机仿真,结果表明在信噪比低于5dB时,其识别率有了明显的提高.
To improve the identification rate between MFSK and MPSK signals, a method of selecting the optimal scale factor was proposed by studying how to select the scale factor. And the identifier between MFSK and MPSK modulation signals were improved. Finally, the simulation was done, and its results show that the identification rate can be enhanced greatly when SNR is below 5 dB.
