| Abstract(in English) | Orthogonal Frequency Division Multiplexing (OFDM)is a promising technique for achieving high bit-rate transmission in radio environments. Various techniques to estimate channel attenuation have been proposed for OFDM transmission. In these techniques, the added pilot semi-blind (APSB) channel estimation has been proposed, which does not require any additional bandwidth. For the transmission of an OFDM packet with preamble, it is difficult to track the channel variation of the latter of packet due to time-varying channels in fast fading environments. We expect that channel estimation is improved without additional bandwidth by applying the APSB channel estimation technique to the last symbol of packet. In this paper, we propose the OFDM packet transmission system using the APSB technique to track the variation of channel attenuations. We show that the proposed system can track the channel variation and achieve better packet error rate (PER) and mean square error (MSE) performance than the conventional 0FDM packet transmission system in fast fading channels. |
