摘要

针对在多普勒环境下LTE-A（改进的长期演进）系统时频域二维稀疏信道的特性

根据导频在时频域的分布以及二者之间的相关性

提出了一种基于OMP（正交匹配追踪）算法改进压缩感知的信道估计。仿真结果表明

改进的OMP算法较原始算法具有更低的MSE（均方误差）。

Abstract

In view of the characteristics of the two-dimensional sparse channel of the time and frequency domains of the LTE-A systems in Doppler environment and in line with the distribution of pilot in the time and frequency domains and its correlation with them

this paper presents an Orthogonal Matching Pursuit（OMP）algorithm-based improved compressed sensing channel estimation by decomposing the search space into ranges between OFDM symbols in time domain and between subcarriers in frequency domain.Simulation results show that the improved OMP algorithm has still lower Mean Square Error（MSE）than the original one.
