Popis:	We proposed a novel equalization technique to suppress noise interference in wireless communications over time varying multipath channels. In the doubly-selective channel, error exists not only in the received signal but also the channel matrix. Total least squares method can be applied to resolve this type problem. Owing to considering the two errors, the total least squares (TLS) method tends to give better results than zero-forcing method based on least square. Through computer simulations, we demonstrate the better performance of the equalizer based on TLS then ZF equalizer.
