Abstract

In this paper the author proposes a method which will allow simple and fast generation of two sets of random variables with given probability mass functions (PMFs) and crosscorrelation sequences (CCS). It is based on the composition of three sets of independent and identically distributed discrete random variables, two of which are correlated with each other only when thelag is null. The method is applicable in cases where, once experimental measurements have established the statistical characteristics of two stationary random processes in terms of PMFs and CCS, it is necessary to implement a simulation model, that is, it is necessary to generate random discrete variables whose PMFs and CCS match the empirical histograms. A case study is given to apply the method proposed to modelling the relationships between the monomedia streams making up a multimedia stream. (C) 1999 Published by Elsevier Science B.V.
