For general exploringobjects requirement, narrow pulse signal with tens millimicro second to millimicrosecond has the frequency spectrum from DC to thousands MHz.
This paper presents a new frequency domain deghosting method on the basis of analyzing both the ghost formation mechanism and its filter spectrum characteristics.
The MDUPC only needs the local information to coordinate intercell interference and achieves the best tradeoff between the fairness of users and the spectral efficiency.
Texture unit and texture spectrum can get the difference of the microtexture and the macrotexture of this two regions effectively so as to detect the target.
In order to study laryngeal phonic function,the methods of acoustic evaluation and phonatory detection has become the focused problem by doctors in otorhinolaryngology and speech pathology.
