一种基于压缩感知的信道估计算法
A Channel Estimation Technique Using CompressedSensing in LTE Systems
摘要
Abstract
Channel estimation is one key technology for wireless communication systems.A new channel estimation technique using compressed sensing（CS） is proposed.CS-based channel estimation exploits a channel＇s delay and Doppler sparseness to reduce the number of pilot signals,and then increase spectral efficiency.Simulation results demonstrate a significant reduction of the number of pilot signals relative to least-square channel estimation.关键词
