OTFS Performance on Static Multipath Channels

IEEE Wireless Communications Letters, 2019
Orthogonal time frequency space (OTFS) modulation is known to achieve excellent error performance in delay–Doppler channels. However, its performance over static multipath channels has never been fully investigated.

Improved De-Multipath Neural Network Models With Self-Paced Feature-to-Feature Learning for DOA Estimation in Multipath Environment

IEEE Transactions on Vehicular Technology, 2020
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.

Multipath Cooperative Routing with Efficient Acknowledgement for LEO Satellite Networks

IEEE Transactions on Mobile Computing, 2019
Multipath 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 ...

Experimenting with multipath TCP

ACM SIGCOMM Computer Communication Review, 2010
It is becoming the norm for small mobile devices to have access to multiple technologies for connecting to the Internet. This gives researchers an increasing interest for solutions allowing to use efficiently several communication mediums. We propose a demonstration of our Multipath TCP implementation for Linux, that allows spreading a single TCP flow ...

Improved Airborne Multipath Modelling

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2018
With the increasing number of satellites broadcasting signals on a second ARNS frequency (L5/E5a) available the dual frequency processing becomes a promising option for the next generation aviation users. In this context, characterizing the error sources of the navigation solution is crucial.

Adaptive CDMA Multipath Delay Trackerfor Closely Spaced Multipaths

2006 IEEE 63rd Vehicular Technology Conference, 2006
CDMA based third generation mobile communication adopts Rake receiver to get diversity gain for multipath signals. This paper first analyzes why traditional CDMA delay tracker fails when multipaths are closely spaced (1-2 chips apart). Then we propose a novel adaptive coherent CDMA tracking loop. This new structure uses an adaptive delay detector which

Short-delay multipath mitigation technique based on virtual multipath

IEEE Antennas and Wireless Propagation Letters, 2005
A virtual multipath (VM) based technique focusing on mitigating both weak and strong short-delay multipath (MP) signals in the global positioning system (GPS) is presented in this letter. Simulations based on the real GPS signal indicate that the proposed technique is able to achieve an absolute range error within 2 m for multipath-to-direct (M/D ...
