Abstract :
Generally in real implementation of OFDM system, the simple and fast LS channel estimation method has been used for the wireless channel in the OFDM systems. If the wireless channel environment were mixed with RoF (Radio Over Fiber) channel, could we still use the conventional least square (LS) channel estimation method for proper communication? Therefore, in this paper, we analyzed that the performance of LS channel estimation where both wireless and RoF channel are coexisted in the OFDM based mobile communication system.
