密集信号分选平面变换技术的多义性分析

信号平面显示变换技术，是根据累积变换的数学原理，得到各种对应信号的特征曲线，累积变换是一对应的，但在用平面变换实现时具有多义性，即有时会出现与某种信号的特征曲线形状相似的特征曲线。作者就平面变换技术多义性的原理进行了分析，论证了产生伪特征曲线的原因，提出了识别伪特征曲线的方法和分选伪特征曲线的方案。

THE MULTI MEANING ANALYSING OF PLANE TRANSFORMATION IN CONCENTRATED SIGNALS SEPARATION

The characteristic curve corresponding signal is obtained in the technique of signal plane transformation based on the mathematical principle of accumulate transform.This separating technique,which tranfers the concentrated signal sequence onto the two dimensional plane,is very intuitive,fast.Accumulate transform is one to one correspondence,but it has multi meaning when used in the plane transformation.That is,sometimes the fake characteristic curve (FCC) on the plane, which is similar to the true characteristic curve may be observed.This paper analyses the principle of multi meaning,demonstrates the cause of the FCC.Meanwhile,this paper presents some methods of distinguishing and separating the FCC.The multi meaning analysing makes the plane transformation more perfect and practical.
