Abstract

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.
