摘要 文章对于离散多音DMT(DiscreteMultitone)系统中量化噪声和削波噪声进行了详细的分析,提出了DMT系统中进行削波率最优设计的原则和方法。仿真结果显示经过不同准则的削波率优化设计后,系统要么提高了性能,要么降低了实现复杂度。 Based on the analysis of clipping noise and quantisation noise in Discrete Multitone(DMT) systems, criterions and methods to optimize the clipping rate in DMT systems are presented in this paper. The simulation results show that the performance is better or the complexity is lower after the clipping rate optimization under different criterions.
