Optimum Quantization in Speech DPCM Systems,
M. Paez, Tildon H. Glisson · Defense Technical Information Center (DTIC) · 1972
The optimum (minimum mean-squared-error) and optimum uniform quantizing characteristics for laplacian- and gamma- distributed signals are given in tabular form. The performance of these quantizers in real speech PCM and DPCM systems is investigated and compared with the obtained when the micro-law quantizing characteristics is used. (Author)
