摘要
在OFDM调制系统中,由于多载波的存在,载波间ICI对信道均衡结果影响很大,同时,采用MMSE信道均衡算法对不同的信道模型也存在均衡误差不稳定的情况。本文提出一种鲁棒的MMSE信道均衡算法,该算法的核心是针对不同信道对信道的PDP进行归一化处理,从而得到在不同类型信道下稳定且鲁棒的信道均衡性能。
In OFDM system, the ICI between the carriers has a serious influence to the channel equalization. On the other hand, considering the MMSE channel equalization algorithm, the equalization MSE results are not stable in different channel models.A robust MMSE channel equalization algorithm is presented in this paper, with the core is that normalizing the PDP of different type of channels, then the MMSE algorithm could get a stable and robust performance in different type of channels.
