Optimization of Cascade Integer Resolution with Three Civil GPS Frequencies
Cascade Integer Resolution Civil GPS Frequencies
2015/6/29
In the near future, there will be two more civil GPS signals in addition to the current one at the L1 frequency (1575.42 MHz). The second civil signal will be broadcast at the L2 frequency (1227.60 MH...
Super-Resolution from Noisy Data

2015/6/17
This paper studies the recovery of a superposition of point sources from noisy bandlimited data. In the fewest possible words, we only have information about the spectrum of an object in the lowfreque...

2015/6/17
This paper develops a mathematical theory of super-resolution. Broadly speaking, superresolution is the problem of recovering the fine details of an object—the high end of its spectrum— from coarse sc...
In single-molecule microscopy it is necessary to locate with high precision point sources from noisy observations of the spectrum of the signal at frequencies capped by fc, which is just about the fre...
