Frequency Domain Equalizer Using 2-Dimensional LMS Algorithm for DWMT-based VDSL System
DWMT 방식의 VDSL 시스템을 위한 2차원 LMS 기법의 주파수 영역 등화기
Abstract
In this paper, we describe the structure of the DWMT (discrete wavelet multitone) transceiver for VDSL system. The DWMT transceiver is basically consisted of the transmultiplexer using cosine modulation filter bank (CMFB), time domain equalizer (TEQ) and frequency domain equalizer (FEQ) minimizing the effects of the transmission channel. For FEQ, we expanded the general LMS algorithm to 2-dimensions: time and subchannel axes and examined the 2-dimensional LMS methods with the various array size.
