基于频谱预处理的RS码盲检测识别方法
RS码 有限域傅立叶变换 盲检测与识别

2014/4/10
针对RS(Reed Solomon)码的盲检测与识别问题，提出了一种基于频谱预处理的检测方法。该方法利用RS码的频域特征，实现对RS码的盲检测与识别，针对高误码情况，对多组码字的频谱分量进行非线性变换和中值滤波，充分利用码字变换频谱的统计信息，使得检测算法可以适应较高的误码环境，同时给出了算法误码适应能力的理论上限。仿真实验表明，算法能够在较高误码率条件下实现对本原RS码的盲检测与识别，性能已接近...
On The Coronal Activity of the RS CVn-Type Binaries
Coronal Activity RS CVn-Type Binaries

2010/4/16
We re-analysed the behaviour of coronal activity of the RS CVn-type binaries as a function of stellar and orbital parameters. Highly significant correlations were found between the x-ray luminosity Lx...
Kinematics of RS CVn and W UMa Binaries in the Hipparcos Catalogue
RS CVn W UMa Binaries Hipparcos Catalogue

2010/4/16
Space motions of RS CVn and W UMa binaries have been calculated using parallaxes and proper motions from Hipparcos catalogue and radial velocities from the literature. We have calculating the mean mot...

2010/4/16
The orbital angular momentum (orbital AM) of a sample of forty RS CVn-type binaries with the orbital periods P \leq 10 days were estimated and the orbital AM distribution with respect to P was critica...
Short-period RS CVn and W UMa binaries: how are they related?
W Ursae Majoris angular momentum loss
font style='font-size:12px;'>
2010/4/16
Two groups of late-type very close main sequence binaries, the so-called short-period RS Canum Venaticorum (RS CVn) and W Ursae Majoris (W UMa) systems, are important for the understanding of the stru...
Co-ordinated Multi-wavelength Observations of the RS CVn System CF Tuc
photometry spectroscopy microwave
font style='font-size:12px;'>
2010/4/16
A `multi-site, multi-wavelength' campaign on the eclipsing RS CVn binary CF Tuc was carried out in 1996 over both optical (photometry and spectroscopy) and radio (microwave) ranges. The microwave data...
