Impulse response shortening for xDSL discrete multitone modems with linear phase filters
نویسندگان
چکیده
The problem of shortening the effective channel impulse response in xDSL is addressed. A new approach is described based on linear phase FIR equaliser filters. The mathematical framework for the LPIRS method is developed and simulation results are presented for several VDSL loops. For a similar performance, the novel method offers a design with considerably lower computational complexity and a simpler solution, on either DSP or dedicated hardware implementations.

Impulse Response Shortening for Discrete Multitone Transceivers using Convex Optimization Approach
In this paper we propose a new criterion for solving the problem of channel shortening in multi-carrier systems. In a discrete multitone receiver, a time-domain equalizer (TEQ) reduces intersymbol interference (ISI) by shortening the effective duration of the channel impulse response. Minimum mean square error (MMSE) method for TEQ does not give satisfactory results. In [1] a new criterion for ...

A partial shortening method of equalization for xDSL is presented. The novel method is suitable for FDD systems, shortening the effective channel impulse response and, additionally, achieving out-of-band noise reduction. A family of solutions based on linear phase FIR equalizers is described. The mathematical framework for all symmetric filters is developed. Channel shortening and bit rate simu...
متن کاملCommunication Theory JOINT IMPULSE RESPONSE SHORTENING FOR DISCRETE MULTITONE SYSTEMS
In Discrete Multitone (DMT) transceivers, a cyclic prefix is inserted between transmitted symbols such that the linear convolution of the data and the channel impulse response becomes a circular one corresponding to term-by-term product in the frequency domain. If the cyclic prefix length is longer than that of the channel impulse response it avoids the intersymbol interference (ISI). To reduce...

This thesis explores three distinct philosophies for improving the efficiency of multi-carrier communication on the digital subscriber loop. The first topic discussed is impulse response shortening for discrete multitone transceivers. The minimum mean-squared error impulse response shortener is reformulated to allow near-optimal rate performance. It is demonstrated that the best existing eigen-...
