Recursive DFT with poly-cosine window
Lenan Wu · Journal of China Institute of Communications · 2001
In this paper, the analysis of the spectrum of the rectangle window function in presented recursive DFT and its effect on the precision of the signal spectrum are made, the recursive DFT with poly-cosine window and its implementation, esecially the initialization of the arithmetic and the computation in part frequency area are presented, the simulation and the discussion about the arithmetic complexity are made.
