Rejection-Sampled Universal Quantization for Smaller Quantization Errors
Chih Wei Ling, Cheuk Ting Li
We construct a randomized vector quantizer which has a smaller maximum error compared to all known lattice quantizers with the same entropy for dimensions 5, 6, ..., 48, and also h…

Vector Quantization with Error Uniformly Distributed over an Arbitrary Set
Chih Wei Ling, Cheuk Ting Li
For uniform scalar quantization, the error distribution is approximately a uniform distribution over an interval (which is also a 1-dimensional ball). Nevertheless, for lattice vec…
