A common practice when analyzing systems using multiple antennas at both ends is to focus on the multipath properties and normalize the SNR out of the channel matrix. This paper studies the relationship between the signal strength and multipath richness using indoor measurements taken at the Brigham Young University campus. It is found that the SNR and the multipath richness can be strongly cor...

New congestion control algorithms are needed for multipath transport protocols such as Multipath TCP, as single path algorithms have a series of issues in the multipath context. One of the prominent problems is that running existing algorithms such as standard TCP independently on each path would give the multipath flow more than its fair share at a bottleneck link traversed by more than one of...

Over-the-horizon radar (OTHR) and microwave radar networks can together generate track data over a wide surveillance region. However the data is often subject to ambiguity and uncertainty due to the complexities of the HF signal propagation environment, which give rise to multipath OTHR tracks, as well as ambiguities in target associations between multiple microwave radars. This report describe...

The Internet is inherently a multipath network for a primary network with only a single path connecting various nodes would have been unbreakable delicate. Unfortunately, conventional Internet technologies have been designed around the preventive assumption of a single working path between a source and a destination. The need of local multipath hold constrains network performance yet as the pri...

Abstract Multipath propagation is a major source of error in global navigation satellite systems (GNSSs), especially urban environments. This because conventional GNSS receivers can provide biased range estimates that lead to positioning errors. In this paper, an Extended Kalman Filter (EKF)-based solution relies on multi-correlator structure proposed replace the delay locked loop (DLL...

Abstract The multipath effect is well known as one of the dominant error sources in most high-precision GNSS applications, its site-dependent and fast-changing nature render it challenging to model mitigate using differencing techniques. However, this study, we present a novel approach signal case oscillatory motion antenna determine characteristics by utilizing signal-to-noise (SNR) ratio meas...

Two major objectives of multipath routing schemes are congestion avoidance and resilience to failures. However, focusing on each objective alone severely deteriorates the quality of the other. More specifically, when multipath routing is employed for congestion avoidance, the traffic is distributed among several different paths, each potentially prone to network failures. Since any path failure...

Multipath is the main systematic error of Global Navigation Satellite System (GNSS) short baseline positioning. cannot be eliminated by double-differenced technique and difficult to parameterize, which severely restrict high-precision GNSS positioning application. Based on spatiotemporal repeatability multipath, sidereal filtering in coordinate-domain (SF-CD), observation-domain (SF-OD), multip...

A content can be replicated in more than one node, in Information Centric Networks (ICNs). Thus, more than one path can be followed to reach the same content, and it is necessary to decide the interface(s) to be selected in every network node to forward content requests towards such multiple content containers. A multipath forwarding strategy defines how to perform this choice. In this paper we...

A new transform domain array signal processing technique is proposed for identification of multipath communication channels. The received array element outputs are transformed to delay–Doppler domain by using the cross-ambiguity function (CAF) for efficient exploitation of the delay–Doppler diversity of the multipath components. Clusters of multipath components can be identified by using a simp...
