A Novel Algorithm for Pilot-Aided Channel Estimation in OFDM Systems
OFDM系统中一种新的导频辅助信道估计算法

The tradeoff between performance and complexity must be taken into account in channels estimation algorithm of wireless OFDM systems. This paper proposes a new algorithm for channel estimation in wireless OFDM systems, which aims at reducing the conventional algorithm complexity by using Wiener filtering combined with interpolation filtering.The analysis and simulation results show that the novel algorithm reduces the complexity remarkably with performance slightly degraded.
