Deterministic Chaotic Propagation Model
IEEE Access, 2023 Coverage prediction is an essential method of planning broadcast and long-range wireless communication systems, minimizing the need for field measurements to adjust the coverage area and consequently reducing the time and cost of implementation. Coverage

Performance evaluation of multipath transport protocol in heterogeneous network environments [PDF]
, 2012 Performance of multipath transport protocols is known to be sensitive to path asymmetry. The difference between each path in terms of bandwidth, delay and packet loss has a potential to significantly decrease the overall performance of a data flow ...

A new multipath mitigation method for GNSS receivers based on antenna array [PDF]
, 2012 the potential of small antenna array for multipath mitigation in GNSS systems is considered in this paper. To discriminate the different incoming signals (Line of sight and multipaths), a new implementation of the well known SAGE algorithm is proposed ...

Multipath Matching Pursuit [PDF]
IEEE Transactions on Information Theory, 2014 In this paper, we propose an algorithm referred to as multipath matching pursuit 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 the ...

Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images [PDF]
, 2010 Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...
