comparison of dem generation and combination methods using high resolution optical stereo imagery and interferometric sar data
DEM/DTM High resolution Combination Fusion Accuracy Multisensor Optical SAR
2015/9/1
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, IKONOS) and...
Noise Suppression for Fiber Radio Transmission on Spectrum-Sliced WDM-PONs Employing Interferometric Structures
Fiber optics communications Radio frequency photonics
2015/5/26
We propose a novel noise-suppression scheme in spectrum-sliced WDM-PONs.Experimentally, low-noise windows can be created in which the noise is reduced by more than 20dB and the performance of vector s...

Sensitivity of Interferometric OSNR Measurements Techniques to the Variation in Signal Extinction Ratio
Sensitivity Interferometric OSNR Measurements Techniques Variation Signal Extinction Ratio
2015/7/31
We discuss calibration requirements for interferometric OSNR measurements. We show that variation of 0.25dB in the signal extinction ratio could result in large errors in OSNR for 42.8Gb/s modulated s...
