A fast encoding algorithm for vector quantization based on Hadamard transform

For vector quantization (VQ), it is extremely time-consuming to extract the similar codeword with input vector during the encoding process. In this paper, a novel algorithm based on Hadamard transform (HT) is proposed. Two inequalities derived after performing HT to all input vectors are used to ear...
