摘要/Abstract

摘要： 提出的辅助判决均衡器在用于滤波多音调制系统时，可克服判决反馈均衡器在多径信道下的地板效应. 同时结合因子图理论给出了辅助判决均衡器的二次判决实现算法，在复杂度增加不大的情况下，解决了其物理可实现性问题.仿真试验表明，辅助判决均衡器在滤波多音调制系统中的性能优于判决反馈均衡器.

Abstract: A decisionaided equalizer(DAE) scheme for filtered multitone (FMT) system is proposed. For FMT system, decisionaided equalizer could overcome the floor effect of decision feedback equalizer which is caused by the multipath channel.A new algorithm based on factor figure is also presented. This algorithm solves casualties of the decisionaided equalizer under the conditions of not improving system complexity much. The simulation results show that this equalizer has a better performance than other FMTs'.

Key words: decisionaided equalizer, decision feedback equalizer , filtered multitone system
