Higher layer coding of non-speech like signals using factorial pulse codebook

Udar Mittal, James P. Ashley, Jonathan Gibbs
2008 Interspeech 2008   unpublished
A transform coding method for coding higher layers of a multi-layer embedded speech and audio coding system using factorial pulse codebook is proposed.  ...  The frequency selective attenuation along with the use of factorial pulse codebook makes the method suitable for coding non-speech like signals.  ...  ) , ( (18) To reduce the complexity of encoding and decoding a low resolution combinatorial approximation function F'(n, r) is used in place of the standard combinatorial function ) , ( r n F .  ...
