| Abstract(in English) | An OFDM system has been used also for wireless local area networks. MIMO space division multiplexing in an OFDM system has been studied to achive high-speed transmission over lOOMbps. In this paper, we compare three methods of channel estimation using a few training symbols. We show that the time-domain minimum square error method that the authors have proposed enables accurate channel estimation. Furthermore, we develop this scheme to estimation of channel and frequency offset between a transmitter and a receiver. We show that the proposed method can estimate them using a preamble that have the same duration as that of the IEEE802.11 a standard. |
