论文摘要
DIRAC-δ分布可以通过汇合序列实现，后者也被视为与身份的近似。本研究提出了所谓的正交前自适应傅立叶分解（POAFD）方法，以实现与身份的快速近似。稀疏表示方法的类型在信号和图像分析以及系统识别中具有潜在的应用。
The Dirac-δ distribution may be realized through sequences of convlutions, the latter being also regarded as approximation to the identity. The present study proposes the so called pre-orthogonal adaptive Fourier decomposition (POAFD) method to realize fast approximation to the identity. The type of sparse representation method has potential applications in signal and image analysis, as well as in system identification.
