单点DFT均衡算法与定点仿真

One-point DFT Equalization Algorit hm and Fixed-point Simulation

均衡技术是在接收端消除无线多径衰落信道引起的码间干扰的重要手段。介绍了一种利用单点DFT算进行均衡的算法,讨论了在对该算法进行定点仿真中遇到的几个问题,最后给出了浮点和定点仿真的结果。

Equalization is an important way to e liminate intersymbol interference that is caused by the wireless fading channel.In this article an equaliza tion algorithmusing one -point DFT i s introduced,and several problems i n fixed -point simu-lation are discussed.Finally,the float -point and fixed -point sim ulation results are given.
