In this paper we consider actions of the free group on two generators. We prove that an action a compact manifold dimension greater or equal to is C0-stable must have t...

The effect of correlated lognormal shadowing on the average probability of error performance of narrow-band wireless sensor network systems with microand macrodiversity reception in a Rician fading channel is investigated by considering a constant correlation model for the shadowed signals at the fusion center or sensor sink of wireless sensor network with radio channel. The performance degrada...

Abstract The site-diversity can be applied to multicarrier-CDMA (MC-CDMA) to improve the bit error rate (BER) performance for a user with weak signal power, resulting in the increased link capacity. In this paper, downlink capacity under shadowing environment is considered when base stations involved in site-diversity operation are determined based on average received power. The impacts of path...

We characterize and describe the extensions of expansive Ano- sov homeomorphisms on compact spaces. As an application we obtain a stability result for Anosov systems, show construction that embeds any system inside having shadowing property pseudo orbits original space.

Deterministic propagation prediction methods proposed for indoor radio are useful for estimating the average propagation loss in real environments, which usually have complicated geometries. On the other hand, these methods generally fail to accommodate human body shadowing, which is a significant propagation effect in indoor picocells. Several empirical models to describe body shadowing have b...

We compare three receivers for coded narrowband transmission over a channel with fading, shadowing , and co-channel interference. The baseline receiver includes conventional diversity reception with maximal-ratio combining. A multiuser approach allows us to derive a maximum-likelihood (ML) multiuser diversity receiver and its reduced-complexity suboptimal version. Finally, a decor-relating dive...

In wireless communication the effect of multipath as well as shadowing takes place simultaneously over the channel and this phenomena leads to composite fading. G-distribution is frequently encountered distribution in wireless fading environment. Combination of multipath fading and shadowing model are used as composite fading model. This composite fading model is named as Gdistribution. G-distr...

AbstractIn this paper, we study local stable/unstable sets of sensitive homeomorphisms with the shadowing property defined on compact metric spaces. We prove that always contain a and perfect subset space. As corollary, generalize results in [Artigue et al. Beyond topological hyperbolicity: Lshadowing property, J. Differ. Equ. 268(6) (2020), pp. 3057–3080.] [Carvalho Cordeiro, Positively N-expa...
