However, Discrete Multi-Tone(DMT) has been selected as the official standard. 但是,分立多音调已被选作正式标准。
Secondly, introduce discrete multi-tone modulation principle in detail, have a systemic and comprehensive analysis and explanation on minimum mean square error ( MMSE ) channel shorten time domain equalizer design methods which are based on all kinds of cost functions, analyze their advantage and disadvantage. 详细介绍离散多音(DMT)频调制原理,对MMSE信道缩短法和基于其他代价函数的时域均衡器设计方法的进行了系统全面的分析和阐述,分析了各自的优缺点;
On the basis of analyzing the discrete multi-tone system structure, an adaptive bit swap algorithm which makes use of the error signal arising from symbol decision for estimating noise energy has been presented. 在分析离散多频调制系统结构的基础上,提出一种利用符号判决后产生的误差信号估计噪声能量,并以此为依据进行自适应比特交换的算法。
We study the theory of Asymmetric Digital Subscriber Loop ( ADSL ), important in Discrete Multi-Tone(DMT) ( DMT ) modulation that is the usual international encoder in ADSL. 本文系统研究了非对称数字用户线的理论,重点研究了国际上对其通用的编码方式&离散多音(DMT)调制(DMT)技术。
As an advanced multi-carrier modulation technique, discrete multi-tone modulation ( DMT ) has many advantages over traditional single-carrier modulation. 离散多音(DMT)调制(DMT)是一种先进的多载波调制技术,较传统的单载波调制具有包括抗频率选择性衰落、抗符号间干扰等诸多优点。
