An improved algorithm for uplink channel estimation
Wang Huahu · 2014
In order to improve the accuracy of uplink channel estimation and reduce the algorithm complex of it,an improved channel estimation algorithm based on the Interpolation filtering algorithm using the Discrete Fourier Transform(DFT)for the Physical uplink shared channel(PUSCH)is proposed in this paper.The new method uses Recursive Least-Squares(RLS)to replace the method based on traditional interpolation filtering.The matlab simulation results show that the new algorithm can effectively balance improving accuracy and reducing complexity of channel estimation algorithm.
