Abstract
A simple and efficient scheme for the compression of vector quantization (VQ) indexes is presented. For an input index, we first develop a searching scheme to find out the matched index from the previous indexes and then send the search order of the matched index to the decoder. Experimental results show that the proposed scheme significantly reduces the bit rate without extra coding error. Moreover, the extra computation introduced is negligible
