Abstract :
In this paper, we present an efficient bit loading algorithm for subband coding. The goal is to effect an optimal distribution of positive integer bit values among various subchannels to achieve a minimum distortion error variance. Existing algorithms in the literature grow with the total number of bits that must be distributed. The novelty of our algorithm lies in the fact that its complexity is independent of the total number of bits to be allocated.
