QoS considerations for DMT-based ADSL and VDSL systems

چکیده
Thanks to their high bandwidth ability, Asymmetric Digital Subscriber Lines (ADSL) and Very high speed DSL (VDSL) am access technologies that permit the transmission of several applications simultaneously on telephonic subscriber lines. Considering that these applications may require a different Quality of Service (QoS), and particularly different Bit Error Rates (BER), for transmission, this paper addresses the problem of providing simultaneously two BERs for transmission over a DMT-based ADSL or VDSL link. Both coded and uncoded systems are considered.

Zipper: a duplex method for VDSL based on DMT
In this paper, we present a new duplex scheme, called Zipper, for discrete multitone (DMT)-based very high bit-rate digital subscriber line (VDSL) systems on copper wires. This scheme divides the available bandwidth by assigning different subcarriers for the upstream and downstream directions. It has high flexibility to divide the capacity between the up and downstream, as well as good coexiste...
متن کاملSignal processor implementation of DMT based VDSL modems
The Discrete Multi Tone (DMT) modulation is considered a viable technique for high-speed digital transmission over subscriber loop. It was selected as the standard for ADSL modems and it is also a strong candidate in the VDSL area. This paper investigates a programmable solution for the DMT based VDSL modems using Texas Instrument processor family TMS320C62xx. A structure for both transmitter a...
متن کاملZipper - a exible duplex method for VDSL I Introduction II The Zipper Duplex Method
A novel duplex scheme for DMT-based VDSL systems on copper wire pairs is introduced. This method, named Zipper, uses different subcarriers in opposite transmission directions to divide the available bandwidth between the two directions. It provides exceptional versatility when it comes to dividing capacity between up and downstream. The scheme has high duplex efficiency, low latency, and most i...
متن کاملA Reduced-Complexity Fast Algorithm for Software Implementation of the IFFT/FFT in DMT Systems
The discrete multitone (DMT) modulation/demodulation scheme is the standard transmission technique in the application of asymmetric digital subscriber lines (ADSL) and very-high-speed digital subscriber lines (VDSL). Although the DMT can achieve higher data rate compared with other modulation/demodulation schemes, its computational complexity is too high for costefficient implementations. For e...
متن کاملFrame Synchronization Exploiting Cauchy Distribution in DMT-Based xDSL Modems
This letter considers frame synchronization in nonsynchronized sampling discrete multi-tone (DMT) based asymmetric digital subscriber line (ADSL)/very high speed DSL (VDSL) systems in the presence of timing error. We propose a frame synchronization method which is based on the observation that the normalized correlation between two sequences separated by the FFT length is Cauchy random variable...
