매우 얕은 바다에서의 실해역 실험 데이터를 이용한 적응 결정궤환 등화기 성능 분석

Abstract

In this paper, we present bit error rate(BER) performance of an adaptive decision feedback equalizer(DFE) with experimental data in a very shallow water. The experiment was performed at the shore of Geoje in November 2007. The BER performance of the adaptive DFE whose tap weight is updated by RLS is described with change of feedforward tap number, feedback tap number, traning seqence length and delay, which shows that the uncoded average BER is and with transmission range 9.7km and 4km, respectively.
