Abstract:
1. A method for combinatorial coding and decoding, the method comprising the steps of: receiving a vector comprising speech, audio, image, or video; receiving a value n based on a number of positions in the vector; receiving a value d based on a number of occupied positions within the vector; generating a logarithmic approximation of a combinatorial function based on n and d; generating a value F′(n,d) based on the logarithmic approximation of the combinatorial function of n and d, such that wherein generating the value comprising generating a value Q′(d), wherein Q′(d) is an approximation of a sum of logarithm of numbers from 1 to d and comprising using the value F′(n,d) to code or decode the vector to produce coded or decoded speech, audio, image, or video.
