Vector permutation encoding for the uniform sources

A vector permutation code (VPC) is defined as a fixed-rate vector quantizer with a codebook C[y/sub 0/] = {y/sub l/}/sub l=0//sup M=1/ consisting of all the distinct permutations of the columns of an L/spl times/n matrix y/sub 0/=(/spl mu//sub 1/,...., /spl mu//sub 1/, ................, /spl mu//sub k/,....., /spl mu//sub k/), where each L-dimensional column-vector /spl mu//sub i/ appears n/sub i/ times. Based on error criterion vector quantisation an algorithm for composition vector design is also proposed.
