针对xDSL传输率较低、传输距离较短的现状,提出了将非正交多重调制(NOMM)技术应用于xDSL中.对NOMM技术在xDSL信道的应用作了全面的计算机仿真研究,并对影响NOMM通信系统传输特性的串音模型展开了分析.仿真结果表明,NOMM通信系统在传输率与传输距离方面具有无可比拟的优越性.
Aiming at the low transmission rate and short transmission distance of xDSL, this paper proposes the application of non-orthogonal multi-modulation (NOMM) technology in xDSL.This paper makes a comprehensive computer simulation study on the application of NOMM technology in xDSL channel, The analysis of the crosstalk model of the transmission characteristics of NOMM communication system shows that the NOMM communication system has unparalleled advantages in terms of transmission rate and transmission distance.
