Soliton distribution

From Wikipedia, the free encyclopedia

A soliton distribution is a type of discrete probability distribution that arises in the theory of erasure correcting codes. A paper by Luby[1] introduced two forms of such distributions, the ideal soliton distribution and the robust soliton distribution.

Ideal distribution

The ideal soliton distribution is a probability distribution on the integers from 1 to K, where K is the single parameter of the distribution. The probability mass function is given by[2]

Robust distribution

The robust form of distribution is defined by adding an extra set of values to the elements of mass function of the ideal soliton distribution and then standardising so that the values add up to 1. The extra set of values, t, are defined in terms of an additional real-valued parameter δ (which is interpreted as a failure probability) and c, . Define R as R=c ln(K/δ)K. Then the values added to p(i), before the final standardisation, are[2]

While the ideal soliton distribution has a mode (or spike) at 2, the effect of the extra component in the robust distribution is to add an additional spike at the value M.
