摘要
提出滤波多音调制 (FMT)中的一种分数间隔预编码技术 ,给出了基于最小均方误差准则 (MMSE)的分数间隔子信道滤波器设计 .这样的设计方法保证了子信道间的正交性 ,而且其结构也比较简单 .在无线传输环境下对FMT中的判决反馈均衡和预编码做了仿真实验 ,并比较了两者的性能 .
A new pre coding structure for Filtered Multitone (FMT) is designed according to the minimum mean square error(MMSE) criterion , while the precoding is performed on a per subchannel basis. This scheme , which is called fractionally spaced precoding, protects the subchannel orthogonalty and has a simple architecture. The performance of FMT DFE and that of FMT precoding are also shown and compared in an example ISI channel.
