Abstract
A model describing the cumulative effect of the independent access of K users to a shared resource, which is formed by N elements, is proposed, based on which an integer interference measure zeta is defined. While traditional cases can be reconducted to reference well-known results, for which zeta is either Gaussian or Poissonian, the proposed model provides a more general framework that offers the tool for understanding the nature of zeta. In particular, an asymptotic closed form expression (K -> infinity, N -> infinity, K/N -> beta is an element of (0,infinity)) for zeta distribution is provided for systems presenting constructive versus destructive interference, and as such is applicable to characterizing statistical properties of interference in a wide range of random multiple access channels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
