MPSKQAM
- 本文深入研究了复杂调制信号MPSK、MQAM的倍号子类以及常用恒包络信 号OQPSK、or／4 QPSK、MSK的调制识别披本。在鳆种基本调制识别方法即基于特征提取的方法和基于最大似然的方法的纂础上采用四种算法分别对上述信号进行识别研究。-This article studies the complex modulation signals MPSK, MQAM number of times and the common sub-class of constant envelope sig

- 基于谱鞘度的包络分析方法在滚动轴承故障特征提取中的应用研究-Application of resonance demodulation in the rolling bearing fault feature extraction based on fast computation of the kurtogram
Stochastic-Frontier
- 随机前沿生产函数DEA方法的特点是将有效的生产单位连接起来，用分段超平面的组合也就是生产前沿面来紧紧包络全部观测点，是一种确定性前沿方法，没有考虑随机因素对生产率和效率的影响。随机前沿生产函数则解决了这个问题。-Stochastic frontier DEA method is characterized by effective production units, with a sub-hyperplane combination of production frontier that is
