A Frequency Domain Approach To Crosstalk identificaion in xDSL Systems



Introduction to DSL


DSL :
High bit rate digital information over telephone subscriber lines
Basic types of DSL
> Basic Rate ISDN (up to 160 kbps)
> HDSL ( up to 1.544 or 2.048 Mbps)
> ADSL (up to 1Mbps(u.s) ,9Mbps(d.s))
> VDSL (up to 52 d.s and 6.4Mbps u.s)

Efficient Frequency Domain Selective Scrambling of Digital Video at java

Abstract:
Multimedia data security is very important for multimedia commerce on the Internet such as video-on-demand and real-time video multicast. Traditional cryptographic algorithms/systems for data security are often not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. This paper presents a joint encryption and compression framework in which video data are scrambled efficiently in the ....etc

Signals are converted from time or space domain to the frequency domain usually through the Fourier transform. The Fourier transform converts the signal information to a magnitude and phase component of each frequency. Often the Fourier transform is converted to the power spectrum, which is the magnitude of each frequency component squared.
The most common purpose for analysis of signals in the frequency domain is analysis of signal properties. The engineer can study the spectrum to determine which frequencies are present in the input signal ....etc
