摘要:
简述ADSL技术的发展历程和国际标准的制定情况,分析ADSL接入模型,介绍了ADSL技术实现的DMT调制解调原理和需要满足的频谱特性.针对G992.2标准,采用大规模专用集成电路设计并实现了符合G.992.2标准的ADSL用户终端,以驱动程序的形式实现了RFC2364和RFC1483协议.设计了测试方案,并对研制的ADSL用户终端进行了测试,测试结果表明设计的ADSL用户终端在传输速率和传输距离上符合要求.
Abstract:
Th is pape r introduces the deve lopm en t o fADSL technology and internationa l standards, ADSL accessm ode. l ForG9921 2, the DMT m odulation, demodu lation, and spectrum character istic are prov ided. U sing large scale integrated circu it, a ADSL user term ina l acco rding to the ITU G. 9921 2 standard is designed, the RFC2364 and RFC1483 as drivers are im plem ented. The test schem e is designed, and the test result show s tha t the ADSL user term inal m ee ts the ITU G. 99212 standard.
