“…This paper proposes a speech signal coding scheme with scalar quantization implemented, where every sample of input signal is processed separately using scalar quantizers [6]. Such an approach is less complex than a vector quantization based approach, which processes input signal samples grouped into the vectors (arrays) and where vectors are quantized at once [35], [20].…”

“…A quantização vetorial (QV) [1], [2], que pode ser vista como uma extensão da quantização escalar em um espaço multidimensional, tem sido utilizada em diversos sistemas de processamento digital de sinais, com um amplo espectro de aplicações, dentre as quais podem ser citadas: compressão de sinais médicos [3], reconhecimento de padrões [4], compressão de voz [5], compressão de imagem [6], esteganografia e marca d'água digital [7], [8].…”
