Performance degradation due to multipath noise for narrowband OFDM systems: channel-based analysis and experimental determination [PDF]
, 2015 The performance of OFDM systems over a multipath channel can strongly degrade due to the propagation delay spread. The distortion of the received signal over the fast Fourier transform window is referred to as multipath noise.

Estimating the Effects of Multipath Selection on Concurrent Multipath Transfer
KSII Transactions on Internet and Information Systems, 2014 Multi-mode device which combines multiple access technologies into a device will offer more cost-effective solution than a sole access implementation. Its concurrent multipath transfer (CMT) technology can transmit media flows over multiple end-to-end paths simultaneously, which is essential to select at least two paths from all available paths.

Multipath Matching Pursuit [PDF]
IEEE Transactions on Information Theory, 2014 In this paper, we propose an algorithm referred to as multipath matching pursuit (MMP) that investigates multiple promising candidates to recover sparse signals from compressed measurements. Our method is inspired by the fact that the problem to find the candidate that minimizes the residual is readily modeled as a combinatoric tree search problem and ...

On the Non-Coherent Wideband Multipath Fading Relay Channel [PDF]
, 2010 We investigate the multipath fading relay channel in the limit of a large bandwidth, and in the non-coherent setting, where the channel state is unknown to all terminals, including the relay and the destination.

Proceedings of the 13th International Conference on emerging Networking EXperiments and Technologies, 2017 Quick UDP Internet Connection (QUIC) is a recent protocol initiated by Google that combines the functions of HTTP/2, TLS, and TCP directly over UDP, with the goal to reduce the latency of client-server communication. It can replace the traditional HTTP/TLS/TCP stack and the IETF has chartered a working group to standardize it.

Frequency estimation in multipath rayleigh-sparse-fading channels [PDF]
, 2004 Maximum-likelihood (ML) data-aided frequency estimation in multipath Rayleigh-fading channels with sparse impulse responses is investigated. We solve this problem under the assumption that the autocorrelation matrix of the pilot signal can be ...

Edge decompositions of multigraphs into multi-2-paths [PDF]
Opuscula Mathematica, 2004 We establish the computational time complexity of the existence problem of a decomposition of an instance multigraph into isomorphic 3-vertex paths with multiple edges.

Intrinsic Identification and Mitigation of Multipath for Enhanced GNSS Positioning
Sensors, 2020 In global navigation satellite system (GNSS)-based positioning and applications, multipath is by far the most obstinate impact. To overcome paradoxical issues faced by current processing approaches for multipath, this paper employs an intrinsic method to

Anomaly Detection for Urban Vehicle GNSS Observation with a Hybrid Machine Learning System
Remote Sensing, 2020 In urban areas, the accuracy and reliability of global navigation satellite systems (GNSS) vehicle positioning decline due to substantial non-line-of-sight (NLOS) signals and multipath effects. Recently, positioning enhancement approaches with supervised
