Partial crosstalk precompensation in downstream VDSL
Very high bit-rate digital subscriber line (VDSL) is the latest generation in the ongoing evolution of DSL standards. VDSL aims at bringing truly broadband access, greater than 52 Mbps in the downstream, to the mass consumer market. This is achieved by transmitting in frequencies up to 12 MHz. Operating at such high frequencies gives rise to crosstalk between the DSL systems in a binder, limiti...
متن کاملPartial Crosstalk Cancellation for Upstream VDSL
Crosstalk is a major problem inmodern DSL systems such as VDSL.Many crosstalk cancellation techniques have been proposed to helpmitigate crosstalk, but whilst they lead to impressive performance gains, their complexity grows with the square of the number of lines within a binder. In binder groups which can carry up to hundreds of lines, this complexity is outside the scope of current implementa...
متن کاملPerformance of Crosstalk Cancellation in VDSL
Crosstalk in DSL leads to significant performance degradation and large loses in data-rate. Several crosstalk cancellation techniques have been proposed to address this problem, however, in the existing literature the analysis of these approaches is based on SNR calculations and the SNR-gap approximation. Furthermore, for crosstalk cancellation techniques based on decisionfeedback, the effect o...
متن کاملA Downstream Crosstalk Channel Estimation Method for Mix of Legacy and Vectoring-Enabled VDSL
—With the latest technology of vectoring, DSL data rates in the order of 100Mbps have become a reality that is under field deployment. The key is to cancel crosstalk from other lines, which is also known as multiuser MIMO cancellation for wireless communications. During the DSL system upgrade phase of field deployment, mix of legacy and vectoring-enabled VDSL lines is inevitable and a channel e...
متن کاملIterative Joint Power Control and Partial Crosstalk Cancellation in Upstream VDSL
Crosstalk is the major limiting issue in very high bitrate digital subscriber line (VDSL) systems in terms of bit-rate or service coverage. At the central office side, joint signal processing accompanied by appropriate power allocation enables complex multiuser processors to provide near capacity rates. Unfortunately complexity grows with the square of the number of lines within a binder, so by...
