Multipath forwarding has been recently proposed to improve utilization in data centers by leveraging its redundant network design. However, most multipath proposals require significant modifications to the tenants’ network stack and therefore are only feasible in private clouds. In this paper, we propose a multipath packet-forwarding scheme for public clouds that does not require any modificati...

a r t i c l e i n f o a b s t r a c t In this paper, a novel algorithm is proposed to achieve robust high resolution detection in sparse multipath channels. Currently used sparse reconstruction techniques are not immediately applicable in multipath channel modeling. Performance of standard compressed sensing formulations based on dis-cretization of the multipath channel parameter space degrade ...

This paper presents network coding based reliable disjoint and braided multipath routing (NC-RMR ) for sensor networks, which forms multipath by hop-by-hop method and only maintains local path information of each node without establishing end-to-end paths. Neighbors of each local node are divided into groups according to their hops to sink nodes to improve the network load balancing. For furthe...

The authors have been proposed a method of very efficient wireless frequency usage. It is based on the measurement of multipath property for each timeslot, and the coherent addition of multipath signals. The method has been implemented an LSI chip. However, the quantitative analysis is remained. In this paper, we prove the effectiveness of this multipath estimation method under the multipath en...

For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...

Clutters caused by multipath have been widely researched in through-the-wall radar imaging (TWRI). The existing research work of multipath only consider reflections from the wall, while in the condition of a small scene, with the increasing number of targets, multipath from targets to targets, named interaction multipath, usually generates ghosts, which degrades the performance of TWRI. In orde...

This paper presents an architecture of Multiband Impulse Radio UWB (MB-IR-UWB) system based on Prolate Spheroidal Wave Function (PSWF) by binary time hopping pulse position modulation (TH-PPM) over multipath fading channel. In order to combat multipath fading, Rake receiver using maximal ratio combining (MRC) is applied to this system, which can successfully capture the unique multipath-rich pr...

Wireless ad-hoc networks are characterized by the lack of infrastructure, use of wireless links with limited bandwidth and frequent topological changes. On-demand multipath routing in wireless ad-hoc networks is effective in providing resilience to route failures and to successful load balancing. Previous work shows that on-demand multipath routing protocols achieve lower end-to-end delay, rout...

Overlapping multipath propagation is one of the main sources of mobile-positioning errors, especially in fast channel fading situations. In this paper we present a technique for detecting the existence of overlapping fading multipath components. Such information is vital for accurate resolving of overlapping multipath components as well as avoiding unnecessary computations and errors in single-...

Multipath and continuous wave (CW) interference may cause severe performance degradation of global navigation satellite system (GNSS) receivers. This paper analyzes the code tracking performance of early-minus-late power (EMLP) discriminator of GNSS receivers in the presence of multipath and CW interference. An analytical expression of the code tracking error is suggested for EMLP discriminator...
