2010 Ubiquitous Positioning Indoor Navigation and Location Based Service, 2010
There are many applications that require continuous positioning in combined outdoor urban and indoor environments. GNSS has been used for a long time in outdoor environments, while indoor positioning is still a challenging task. One of the major degradations that GNSS receivers experience indoors is the presence of multipath. The current paper analyzes

Journal of the Audio Engineering Society, 2016
The localization of beat instants is often based on some low-level rhythmic feature extracted from the audio signal (usually an onset detection function), as well as the tempo path that is estimated from it. Going from such descriptors to a sequence of beat instants requires a tracking strategy that models how the beat evolves and offers a good trade ...

Multipath Estimating Delay Lock Loop for LTE Signal TOA Estimation in Indoor and Urban Environments
IEEE Transactions on Wireless Communications, 2020Long-term evolution (LTE) signals are potential signals-of-opportunity for position and navigation, especially in challenging urban and indoor environments. A major challenge is that the LTE signal time-of-arrival (TOA) estimations are susceptible to the

Direction of arrival (DOA) estimation of underwater multipath signals has become an indispensable part of many military and civil applications in the oceanic field. However, DOAs of different paths of the multipath signals may be the same or too close to

Multipath Cooperative Routing with Efficient Acknowledgement for LEO Satellite Networks
IEEE Transactions on Mobile Computing, 2019Multipath routing can significantly improve the network throughput and end-to-end (e2e) delay. Network coding based multipath routing removes the complicated coordination among multiple paths so that it further enhances data transmission efficiency ...

Multipath solutions have been shown to help improve throughput, reliability and/or load balancing. This paper seeks to understand if and when they benefit rate stability. Rate stability is important to many real-time, interactive applications, e.g., streaming video, but whether multipath solutions can help is unclear.

When the elevation of target is smaller than a beamwidth, the complex multipath signals will distort the feature of direct signal reflected from target. The elevation of target can hardly be estimated accurately.

On beamforming in presence of multipath
ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005We consider a source radiated signal arriving at an array as a group of wavefronts, each having a different angle of arrival and with arbitrary amplitude, phase and inter wavefront correlation. Several such sources may be present and the measurement data is assumed to be corrupted by sensor to sensor uncorrelated noise. The task of the beamformer is to

Control of Multipath TCP and Optimization of Multipath Routing in the Internet
2009There are moves in the Internet architecture community to add multipath capabilities to TCP, so that end-systems will be able to shift their traffic away from congested parts of the network. We study two problems relating to the design of multipath TCP.

MultiFath TCP (MPTCP) is a recent TCP extension that enables hosts to send the data belonging to one connection over multiple paths. It is already deployed for various use cases, notably on smartphones. In parallel with this, there is a growing deployment of encryption and authentication techniques to counter various forms of attacks.
