Crosstalk analysis in digital subscriber line by evaluating power spectral density function

Abstract

Digital Subscriber Line (DSL) combines the advantages of providing fast means of internet access with the usage of an existent infrastructure known as the plain old telephone service (POTS). Transmissions that use higher frequencies are more subject to attenuation and to crosstalk. Crosstalk is the undesired radiation of energy among wires. It is more likely to occur among/between similar frequencies and results in a received wave form that differs from the original wave form that was sent. In this article we analysis the crosstalk in various DSL systems by evaluating power spectral density function, i.e. functional principles of DSL and impairment caused by crosstalk. It is performed by the analysis of the results obtained from the Matlab program.
