The paper studies channel estimation methods with DRS in an OFDM system. As the DRS may only locate on part of the bandwidth, conventional methods, such as 2D Wiener filter and DFT based time domain estimation, cannot function well. A weighted averaging channel estimation method is proposed by which the channel responses estimated by LS estimation is averaged using Lagrange method. To verify the efficiency...
