Abstract(in English) | The DFT and the IDFT are often performed on sequences,which contain many zeros.Typical examples,considered in this report are time-domain interpolation and the computation of linear convolution.To achieve efficiency the operations on zeros must be eliminated.Such techniques exist for the complex-valued FFT algorithms.In the majoritr of practical cases real signals are processed.Then real-valued algorithms,that involve real arithmetic are more suitable.In the report we demonstrate that pruning can be applied to the real-valued algorithms as well.Three algorithms are considered:radix 2,split-radix and Bruun′s FFT. |
