Summary:
The subband coding (SBC) using the multirate filter bank. This paper proposed two methods to find out sets of decimation ratios, and an optimal set is chosen for designing multirate filter bank of subbank coder. Because the optimal set is suitable with PSD distribution of signal, the achieved result does not help only to decrease data rate but also to reduce total error on the reconstruted output signal.
