Symbol Time Error and Channel Estimation in Wireless OFDM LAN/MAN

摘要：

OFDM is a promising high-speed data transmission platform, and wireless OFDM LAN/MAN has rapidly developed since some OFDM network technologies were standardized. In this paper, the wireless OFDM LAN/MAN topological structures are described, and a novel symbol time error and channel estimation algorithm for the wireless OFDM LAN/MAN based on the PSD estimation is presented. The results of simulation prove the mean and variance of data symbol time error estimation based on the PSD estimation is low, and the channel estimation based on the PSD estimation is more precise than the LS estimation.
