Using FFT for Error Correction Decoders
Farokh Marvasti, Mohammed Nafie · 1993
The discrete Fourier transform (DFT) is used for error detection and correction. An iterative decoder is proposed for erasure and impulsive noise which also works with moderate amount of additive random noise. The iterative method is very simple and efficient consisting of modules of fast Fourier transforms (FFT) and inverse FFTs. This iterative decoder can be implemented in a feedback configuration. The authors are working on a DSP implementation of this technique.
