Index mapping approach of deriving the PM DFT algorithms
D. Sundararajan, M. Omair Ahmad · IEEE Transactions on Computers · 1998
Recently, it has been shown that radix-2 DFT algorithms can be designed based on vector representation of data providing several advantages. In this paper, an index mapping approach is used to derive these algorithms. This approach makes the derivation simpler and provides a better insight into the functioning of the algorithms. The computational complexity and the performance of the software implementation of the algorithms are also presented.
