Tóm tắt

In this paper, we propose a transceiver design for the ETSI VDSL standard that uses the discrete multi-tone (DMT) modulation. Algorithms for channel estimation/equalization, symbol synchronization, sampling clock tracking are designed and integrated into the receiver architecture. Fixed-point simulation of the whole system shows that the proposed receiver architecture is capable of very high-rate transmission in digital subscriber loop channels.
