【摘要】 对于设计一个DMT(离散多频音)系统来说,两种最关键的技术就是带宽优化算法的选择和前置时域均衡器的设计。文中就时域均衡器的设计,介绍了两种算法:基于迭代的TEQ(时域均衡器)算法和基于IDFT/DFT(离散傅里叶逆变换/离散傅里叶变换)的循环均衡算法,并且对两种算法进行了理论分析和计算机仿真,给出了仿真结果。更多还原

【Abstract】 Two of the most crucial elements in a successful design of a DMTADSL system are the selection of bandwidth optimization algorithm and the designation of timedomain equalizer. In this paper, we describe two algorithms: TEQ algorithm based on iteration and TEQ cycle algorithm based on DFT/IDFT. Meanwhile the theoretical analysis and computer simulation are presented .The simulation results are given.更多还原
