While the discrete Fourier transform also provides a frequency-domain representation, its decorrelating performance is only approximate. Although this is good enough for many applications, in applications which require relatively short windows, such as speech and audio processing, the penalty due to the approximate decorrelation limits overall performance. This paper focuses on the practical implementation of the Vandermonde transform. Our purpose is to provide a short review of state-of-the-art methods, a step-by-step instructions for implementation and an evaluation of the performance.} } @inproceedings{backstrom2014decorrelated, title={Decorrelated Innovative Codebooks for {ACELP} Using Factorization of Autocorrelation Matrix}, author={B{\"a}ckstr{\"o}m, Tom and Helmrich, Christian R.}, booktitle=interspeech, year={2014}, } @misc{backstrom2014apparatus, title={An apparatus for encoding a speech signal employing {ACELP} in the autocorrelation domain}, author={Bäckström, Tom and Multrus, Markus and Fuchs, Guillaume and Helmirich, Christian and Dietz, Martin}, year={2014}, month=apr #
