相位突变 meaning in Chinese

phase hits
phase jump

So the likelihood function of the differential phase peaks can be formed as means to identify m - ary psk
于是可利用相位突变峰值的似然函数来识别信号为哪一种进制的psk信号。
Also , the intra - class classification of m - ary fsk and m - ary psk have been made . based on the number of different frequencies it is easy to identify m - ary fsk signals
对于fsk信号，利用其不同频率的个数可以完成其类内识别，而psk信号则可以利用它的相位突变信息进行类内识别。
As for the m - ary psk signals , the differential phase peaks at the transients are used . the pdf ( probability density function ) of the differential phase peaks of m - ary psk are the mean of m - 1 pdfs of m - 1 phase peaks
由于进制的数字调相信号每个子码间具有个相位突变，其相位突变的峰值满足一个概率密度为的分布，若信号为元psk信号，则相位突变峰值的概率密度函数就是个概率密度之和的平均。
In chapter two we study the transport properties of a curved quantum wire , such as the mixture of transverse modes , suppress of conductance , local density , abrupt change of transmission phase and so on . these properties is compared to those of a perfect quantum wire
第二章分析了弧形量子线的模式混合，电导抑制，局域态密度，透射相位突变等性质，并将这些性质与理想直量子线进行了对比。
