| 摘 要： | 根据线性预测具有良好的抗窄带干扰性能但无法抑制多径干扰的特性,提出了一种窄带干扰和多径干扰抑制的级联算法即CNMS算法,理论分析表明本算法可以获得比线性预测算法更高的性能增益。仿真结果说明,CNMS算法在优于线性预测算法的同时还优于线性均衡算法。

| Abstract: | Although linear prediction can suppress the NBI,it can't suppress the Multipath interference.According to this char- acter,a CNMS(Concatenated Narrow band interference and Multipath interference Suppression)algorithm is proposed.It is shown by the- ory analysis that the performance gain of the CNMS algorithm is higher than the linear prediction algorithm.Simulation results show that CNMS algorithm is not only superior to linear prediction but also better than the linear equalization algorithm. |
