A Vector Quantizer for the Laplace Source
Date of Original Version
It is well known that vector quantizers (VQ's) can have substantial gain in performance over scalar quantizers; however, due to their complexity, optimal VQ's are often limited to low bit rate/dimension situations. A low complexity, nearly optimal VQ for the independent Laplace source is presented. Both moderate and high bit rate results are included (greater than one bit per dimension). The VQ is a generalization of Fischer's pyramid VQ and is similar in structure to the unrestricted polar quantizers previously presented for the independent Gaussian source. © 1991 IEEE
