Crosstalk is the major source of performance degradation in VDSL. A number of crosstalk cancellation techniques have been proposed to address this. Whilst these schemes lead to large performance increases they also have high run-time complexities, a problem which grows rapidly with the number of lines within a binder. Since the majority of crosstalk typically comes from only a few dominant cros...

This paper presents the results of a detailed investigation of various crosstalk scenarios in VDSM technologies by using a distributed model of the crosstalk site while. As example of these results, it is stated that the combination of one crosstalk event at a site and another crosstalk event at a different site in the transitive fan-out of the first site may cause a slowdown or speedup of the ...

The ACS/WFC detector consists of two CCDs, each of which is read out through two amplifiers. While reading each quadrant of the detector, the electronic crosstalk between the amplifiers induces faint, typically negative, mirror-symmetric ghost images on the other three quadrants. The effect is strongest for high-signal offending (source) pixels. Analysis of the pre-SM4 crosstalk showed that its...

Crosstalk between multiple services transmitting through the same telephone cable is the primary limitation to digital subscriber line services. From a spectrum management point of view, it is important to have an accurate map of all the services that generate crosstalk into a given pair. If crosstalk is measured via modem-based methods, i.e., while a digital subscriber line (DSL) system is run...

Optical crosstalk is a major factor limiting the performance of Geiger-mode avalanche photodiode (GmAPD) focal plane arrays (FPAs). This is especially true for arrays with increased pixel density and broader spectral operation. We have performed extensive experimental and theoretical investigations on the crosstalk effects in InP-based GmAPD FPAs for both 1.06-μm and 1.55-μm applications. Mecha...

Received Apr 2, 2013 Revised May 28, 2013 Accepted Jun 14, 2013 Crosstalk noise is often induced in long interconnects running parallel to each other. There arises a need to minimize the effect of these crosstalk noise so as to maintain the signal integrity in interconnects. So in this paper crosstalk noise is minimized using various techniques such as repeater (bidirectional buffer) insertion ...

Studying binocular vision requires precise control over the stimuli presented to the left and right eyes. A popular technique is to segregate signals either temporally (frame interleaving), spectrally (using colored filters), or through light polarization. None of these segregation methods achieves perfect isolation, and so a degree of crosstalk is usually apparent, in which signals intended fo...

We investigated the influence of inter-electrode spacing on the degree of crosstalk contamination in surface electromyographic (sEMG) signals in the tibialis anterior (target muscle), generated by the triceps surae (crosstalk muscle), using bar and disk electrode arrays. The degree of crosstalk contamination was assessed for voluntary constant-force isometric contractions and for dynamic contra...

The emerging multiuser transmission techniques for enabling higher data rates in the copper-access network relies upon accurate knowledge of the twisted-pair cables. In particular, the square-magnitude of the crosstalk channels between the transmission lines are of interest for crosstalk-mitigation techniques. Acquiring such information normally requires dedicated apparatus since crosstalk-chan...

Crosstalk noise is often induced in long interconnects running parallel to each other. There is a need to minimize the effect of these crosstalk noise so as to maintain the signal integrity in interconnects. In this paper crosstalk noise is minimized using various techniques such as repeater (bidirectional buffer) insertion along with shielding, skewing and shielding & skewing simultaneously. W...
