Improved Channel Estimation for OFDM Systems by Exploiting Ordered Space

摘要：

　　In this paper,we propose an improved channel estimation method for orthogonal frequency division multiplexing (OFDM) systems in sparse multipath fading channels.The proposed method transforms the channel estimates into an ordered space and uses the minimum description length (MDL) criterion to estimate the number of paths and the path positions.Simulation results demonstrated that an improved channel estimation performance is obtained due to the reduction of signal space.
