| 摘 要： | DSL技术是当前主流的宽带接入技术,串音干扰是制约DSL系统传输性能的重要因素。提出一种利用MIMO技术降低DSL系统中串音干扰的方法。在分析串扰对线路影响的基础上,建立了基于离散多音调制下的MIMO信道模型,应用奇异值分解法消除串扰,采用注水算法解决了MIMO-DSL信道的功率分配问题。Matlab仿真结果表明,其速率可以达到non-MIMO信道的1.5倍,有效降低了DSL系统串音干扰的影响。 |
| 关 键 词： | 多输入多输出 数字用户复接线 远端串扰 注水算法 |

| Abstract: | DSL is the major network access technique,crosstalk is one of the main limitations in the rates achievable by digital subscriber line(DSL) systems.A method of using the multiple-input multiple-output(MIMO) transmission technique to reduce the crosstalk in the DSL system.The MIMO channel model based on discrete multi-tone modulation is built by analyzing impact of crosstalk on line,the crosstalk is canceled by singular value decomposition,the power allocation of MIMO-DSL channel is resolved by the water-fill... |
| Keywords: | MIMO DSL far-end crosstalk water-filling |
