Reduction of quantization noise via periodic code for oversampled input signals and the corresponding optimal code design

An analytic model for quantized discrete transform error

“…Although many different problems arising in connection with image [12,16,18,19,22,23], video [14] and speech [13] processing have need of quantization effect analysis, and although the very analysis has quite a rich history, being elaborated in earlier works such as [5,7] and then constantly advanced by research efforts such as [2,3,5,6,11,16,17,20,21,24,25], the special question of quantization under a linear transformation has apparently not yet been studied in depth.…”
