Application of the discrete Laguerre transform to speech coding
Giridhar D. Mandyam, Nasir Udin Ahmed, Neeraj Magotra · 2002
The discrete Laguerre transform (DLT) displays characteristics which make it amenable to the coding of speech. In this paper, the DLT is used in a classic transform coding method for speech and compared to the discrete cosine transform (DCT), which has been widely applied to speech coding. The results show promise, as the DLT outperforms the DCT at very low bitrates.
