An improved optimal bit allocation method for sub-band coding
This paper presents an improved optimal bit allocation method for sub-band coding. To speed up the allocation process. a coarse bit range for each sub-band is firstly obtained using the log-variance method, and then an optimal searching routine is applied to produce the final solution. Good features are showed in the simulations for evaluating the proposed method. (C) 2003 Elsevier B.V. All rights reserved.
