| 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 the filtered multitone(FMT) system is proposed.For the FMT system,a decision-aided equalizer could overcome the floor effect of the 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'. |
