Fast search algorithm of adaptive code-book for speech coding
Li Fan · Computer Engineering and Applications Journal · 2007
Code Excited Linear Prediction(CELP) can provide high voice quality at low bit rates,but it has high computational complexity.Adaptive code-book search plays an important role in most CELP by replacing long-term prediction.In this paper a new adaptive code-book search algorithm is applied for the conventional algorithm of 4.8 kbp FS1016 and the new algorithm can significantly simplify the computation of code-book search.
