Tighter and Stable Bounds for Marcum Q-Function
This paper proposes new bounds for Marcum Q-function, which prove extremely
tight and outperform all the bounds previously proposed in the literature. What
is more, the proposed bounds are good and stable both for large values and
small values of the parameters of the Marcum Q-function, where the previously
introduced bounds are bad and even useless under some conditions. The new
bounds are derived by refined approximations for the 0th order modified Bessel
function in the integration region of the Marcum Q-function. They should be
useful since they are always tight no matter the parameters are large or small.Comment: 7 pages. Submitted to IEEE Transactions on Information Theor
