Achievable rates for additive isotropic α-stable noise channels

Résumé

Impulsive noise arises in many communication systems-ranging from wireless to molecular-and is often modeled via the alpha-stable distribution. In this paper, we investigate properties of the capacity of complex isotropic alpha-stable noise channels, which can arise in the context of wireless cellular communications and are not well understood at present. In particular, we derive a tractable lower bound, as well as prove existence and uniqueness of the optimal input distribution. We then apply our lower bound to study the case of parallel alpha-stable noise channels and derive a bound that provides insight into the effect of the tail index ff on the achievable rate.
