A Non-Feedback-Loop and Low-Computation- Complexity Algorithm Design for a Novel 2-D Sliding DFT Computation

This paper presents a forward-path, novel, two-dimensional (2-D) sliding discrete Fourier transform (SDFT) algorithm based on the column-row 2-D DFT concept and the shifted window property. After applying a descending dimension method (DDM), a mixed-radix and butterfly-based structure can be further...
