Channel estimation in MIMO-OFDM systems based on comparative methods by LMS algorithm
In mobile telecommunication systems, a channel estimating method which is able to follow its changes at any moment, quickly, precisely and with less calculating operations, is a mater of high significance. The aim of this paper is to investigate and propose a channel estimation method for MIMO-OFDM systems based on comparative methods. According to this, with investigating the channel estimation method, we can design optimum training courses for these systems and introduce related comparative methods based on LMS algorithm. The efficiency of suggested LMS algorithm can be investigated by simulation and the results of estimation will come to a comparison.
