VDSL2信道建模与仿真

Modeling and Simulation for VDSL2 Channel

从传输线理论出发,运用基尔霍夫定律建立了传输线方程.应用传输线方程建立双绞线信道模型,并对该模型在0～30MHz频段进行了仿真分析,且将仿真结果与法国电信研发部的实测数据进行了比较,结果证明模型与实测数据一致,因此表明所建模型符合实际情况.该模型的建立对VDSL2系统研究、性能分析和系统设计有着重要的作用和意义.

DSL technology transmit data through Twisted Pair lines at higher speed. Based on the transmission line theory, transmission line equation is set up by applying Kirchhoff law, through which the Twisted Pair line channel model is proposed. Computer simulation results from the developed models and France Telecom R＆D measured channels are compared. These results reveal that the proposed model can well match the measured channel data, and also be in agreement with the real cases. This model may render as a useful reference for VDSL2 system research and design.
