  • sharp bounds on the entropy of the Poisson Law and related quantities
    IEEE Transactions on Information Theory, 2010
    Co-Authors: José A. Adell, Alberto Lekuona
    Abstract:

    One of the difficulties in calculating the capacity of certain Poisson channels is that H(?), the entropy of the Poisson distribution with mean ?, is not available in a simple form. In this paper, we derive upper and lower bounds for H(?) that are asymptotically tight and easy to compute. The derivation of such bounds involves only simple probabilistic and analytic tools. This complements the asymptotic expansions of Knessl (1998), Jacquet and Szpankowski (1999), and Flajolet (1999). The same method yields tight bounds on the relative entropy D(n, p) between a binomial and a Poisson, thus refining the work of Harremoe?s and Ruzankin (2004). Bounds on the entropy of the binomial also follow easily.

    Abstract:

    One of the difficulties in calculating the capacity of certain Poisson channels is that H(lambda), the entropy of the Poisson distribution with mean lambda, is not available in a simple form. In this work we derive upper and lower bounds for H(lambda) that are asymptotically tight and easy to compute. The derivation of such bounds involves only simple probabilistic and analytic tools. This complements the asymptotic expansions of Knessl (1998), Jacquet and Szpankowski (1999), and Flajolet (1999).

  • Statistics of Return Times:¶A General Framework and New Applications
    Communications in Mathematical Physics, 1999
    Co-Authors: Masaki Hirata, Benoît Saussol, Sandro Vaienti
    Abstract:

    In this paper we provide general estimates for the errors between the distribution of the first, and more generally, the K th return time (suitably rescaled) and the Poisson Law for measurable dynamical systems. In the case that the system exhibits strong mixing properties, these bounds are explicitly expressed in terms of the speed of mixing. Using these approximations, the Poisson Law is finally proved to hold for a large class of non hyperbolic systems on the interval.
