Software-based Multipath Mitigation: Sampling for Multipath Invariance
Software-based Multipath Mitigation Sampling Multipath Invariance
2015/6/29
Multipath potentially introduces a significant bias error into GPS code phase positioning solutions. That error is dependent on the amplitude, delay, phase, and phase rate of the multipath with respec...
The Multipath Invariance Approach for Code Multipath Mitigation
Multipath Invariance Approach Code Multipath Mitigation
2015/6/29
The concept of multipath invariance asserts that there exist properties and/or regions of the code correlation function that do not change as a function of the multipath amplitude, delay, phase and ph...
In this paper, we present a general algebraic framework for analysing decentralized control systems. We consider systems defined by linear fractional functions over a commutative ring. This provides a...
Quadratic Invariance is Necessary and Sufficient for Convexity
Convexity Necessary and Sufficient
2015/6/19
In decentralized control problems, a standard approach is to specify the set of allowable decentralized controllers as a closed subspace of linear operators. This then induces a corresponding set of o...
PHOTOGRAMMETRIC INVARIANCE
Image transfer Mathematical models Orientation Photogrammetry Reconstruction
2014/12/31
Two tasks, image transfer and object reconstruction, are investigated using three different approaches. The first approach, based on the fundamental (F) matrix, compares the use of all three F matrice...

This paper formulates and proves two types of necessary and sufficient
conditions for the characterization of positively (flow) invariant sets with respect to the
state-space trajectories of the tim...
