波包理論-
The other is the local cosine bases developed as a kind of orthogonal basis based on the fourier analysis and wavelet - packet theory. in this thesis, theoretical analysis and numerical applications are mainly focused on the beamlet - domain wave field extrapolation using g - d frame propagators. the whole thesis consists of six chapters
通過對具體信號的分析,對不同變換方法的信號表示效率進行了對比,並總結了g - d框架及對其進行尺度擴展組成的gabor函數族在應用於波場相關的研究中時,優于其它正交分解方法的特性。
