signal to quantization noise ratioIn this paper, the design procedure of the piecewise uniform scalar quantizer having segments with widths that form a geometric progression is presented. The proposed quantizer design optimization for the Laplacian source of the unit variance is performed by optimizing ...
Asymptotic Analysis Of Lattice-Based Quantization The gain of optimal companding compared to scalar quantization is shown to be the gain in normalized moment of inertia of the lattice cell compared to a cube. The third part considers uniform polar quantization, which utilizes a polar... PW Moo ...
摘要: Using a recent result on the support of uniform scalar quantization, we optimize uniform polar quantization by choosing the asymptotically optimal support of the magnitude quantizer and deriving the optimal rate allocation between the magnitude and phase quantizers...

Rate-Quantization and Distortion-Quantization Models of Dead-Zone Plus Uniform Threshold Scalar Quantizers for Generalized Gaussian Random Variables This paper presents the rate-distortion modeling of the dead-zone plus uniform threshold scalar quantizers with nearly-uniform reconstruction quantizers (D......
Consider a non-uniform scalar quantizer with four possible quantization values. Assuming the quantization code book is P={P1, . . . P4}, where Pi<Pi+1 for i=1, 2, 3 and each Pi occurs with probability p(Pi)=Pi for i=1, . . . , 4. Define Dij=|P-Pj|2. Along the lines of...

The quantization process rounds both positive and negative inputs downward to the nearest quantization level, with the exception of those that fall exactly on a quantization boundary. It quantizes the real and imaginary components of complex inputs independently. In the second step, the block ...
