Blind channel estimation of MIMO-OFDM systems in satellite communication

摘要

Channel effects on the signal which has been sent from the transmitter to the receiver causes us to need accurate information of the channel, to detect the signal in the receiver. According to this issue we use the channel estimation techniques to obtain the channel information. In this paper blind channel estimation method for MIMO-OFDM systems in satellite communication has been investigated. Also the performance of this method has been verified based on the bit error rate and the least square error, using the simulation results.
