A PRELIMINARY INVESTIGATION ON COMPARISON AND TRANSFORMATION OF SENTINEL-2 MSI AND LANDSAT 8 OLI Timely and accurate earth observation with short revisit interval is usually necessary, especially for ...
APPLYING 3D AFFINE TRANSFORMATION AND LEAST SQUARES MATCHING FOR AIRBORNE LASER SCANNING STRIPS ADJUSTMENT WITHOUT GNSS/IMU TRAJECTORY DATA
Airborne Laser Scanning adjustment LIDAR georeferencing quality control
2014/6/5
In this article we extend our previous work on the topic of ALS strip adjustment without GNSS/IMU trajectory data. Between overlap- ping strip pairs the relative orientation as a 3D affine trans...
OTDM-WDM Conversion Based on Time-Domain Optical Fourier Transformation with Spectral Compression
Optical communications Nonlinear optics four-wave mixing.
2015/5/21
We propose a scheme enabling direct serial-to-parallel conversion of OTDM data tributaries onto a WDM grid, based on optical Fourier transformation with spectral compression.Demonstrations on 320 Gbit...
Electronic dispersion compensation by Hadamard transformation
Modulation Optical communications Dispersion
2015/6/10
We demonstrate that the Hadamard transform can be applied to look up table (LUT)-based predistorters to simultaneously compress and optimize the LUT for dispersion-limited links.
640 Gbit/s Single-Polarization DPSK Transmission over 525 km with Time-Domain Optical Fourier Transformation in a Round-Trip Configuration
Fiber optics communications Multiplexing
2015/6/8
A 640 Gbit/s single-polarization DPSK signal was transmitted over 525 km in a single channel. Time-domain optical Fourier transformation in a round-trip configuration greatly enhanced the tolerance to...
