TL;DR: The coder structure is described in detail and the reasons behind certain design choices are discussed and a summary of the subjective test results based on a real-time implementation of this version are presented.
Proceedings ArticleDOI
Fast CELP coding based on algebraic codes
TL;DR: The paper describes a related scheme, which allows real time implementation on current DSP chips, and the very efficient search procedure in the codebook is achieved by means of a new technique called "backward filtering" and the use of algebraic codes.
Proceedings ArticleDOI
16 kbps wideband speech coding technique based on algebraic CELP
TL;DR: An efficient procedure for searching such a large codebook deploying a focused search strategy, where less than 0.1% of the codebook is searched with performance very close to that of a full search is described.
Proceedings ArticleDOI
On reducing computational complexity of codebook search in CELP coder through the use of algebraic codes
TL;DR: A backward filtering formulation is given to show that sparse algebraic codes (SACs) offer distinct advantages and it is shown that they reduce the optimal-search computation per codeword.
Journal ArticleDOI
A toll quality 8 kb/s speech codec for the personal communications system (PCS)
TL;DR: A toll quality speech codec at 8 kb/s suitable for the future personal communications system and can support a frame erasure rate up to 3% with a degradation in its performance that is still worse than the ITU-T requirements.
