High-frequency characterization of twisted-pair cables
A wave propagation method model is proposed for the extraction of propagation parameters of high-bit rate digital subscriber twisted-pair cables. The model is derived from the scattering parameters of a transmission line. The frequency dependence and the skin effect are studied. Experimental simulations are performed to evaluate the accuracy of the extracted parameters. Good agreement is found ...
متن کاملElectromagnetic coupling of twisted pair cables
Increasing deployment of digital subscriber line (DSL) technology operating in the long wave, medium wave and sometimes short wave frequency ranges, has raised the question of how such systems interact with rival radio frequency sources and equipment. Two of the major standards bodies in the field, ITU and ETSI, imposed by the standardization of such promising technologies like ADSL, SHDSL and ...
متن کاملSending A/V Signals Over Twisted Pair Cables: An Introduction
A/V over twisted pair is the transmission and distribution of audio and analog video, as well as control signals over wiring traditionally associated with data networking and telephone systems. This wiring is commonly known as UTP, or unshielded twisted pair. Special interfacing equipment is required to send video and audio signals over UTP wiring. UTP-based A/V systems are appealing for many a...
متن کاملDeep-LMS for gigabit transmission over unshielded twisted pair cables
In this paper we propose a rapidly converging LMS algorithm for crosstalk cancellation. The architecture is similar to deep neural networks, where multiple layers are adapted sequentially. The application motivating this approach is gigabit rate transmission over unshielded twisted pairs using a vectored system. The crosstalk cancellation algorithm uses an adaptive non-diagonal preprocessing ma...
متن کاملReduction of guard interval by impulse compression for DMT modulation on twisted pair cables
In multicarrier modulation schemes like Orthogonal Frequency Division Multiplex (OFDM) or Discrete Multi Tone (DMT) a guard interval represented by a cyclic prefix (CP) is inserted between successive multicarrier symbols in order to reduce intersymbol interference (ISI). The length of the guard interval is determined by the length of the channel impulse response (CIR). For a fixed guard interva...
