Abstract

In wireless OFDM applications, since the radio channel is frequency selective and time-varying, a dynamic estimation of channel must be achieved before the demodulation of the transmitted OFDM signals. As an effective approach for solving the channel estimation problems, the pilot-assisted channel estimation technique has received considerable attention in recent years. In this paper, we investigate the channel estimation error in the existing pilot-assisted channel estimation approaches in detail, a new effective channel estimation approach with lower estimation error is proposed as well.
