| 摘 要： | 针对DMT ADSL（DMT线路码非对称数字用户环路）传输系统发送信号幅值尖峰问题。本文提出了一种降低发送信号最大峰值同时又不损失系统 传送信息的非线性映射方法。通过最优化方法合理地设计一组可逆映射器，该方法比目前ADSL系统的硬限幅方法能较大幅度地压缩系统的动态范围或在相同的动态范围下获得更好的传输性能。

| Abstract: | Focus on the large amplitude peak problem in multicarrier transmission system,a non linear mapping method to reduce the peak and did not lose information at the same time is proposed in this paper Using optimization method to design the reversible mapping function,the dynamical range of the system can be depressed greatly or higher performance can be implemented against the traditional clipping method |

| Keywords: | multicarrier transmission non linear mapping clipping optimization |
