PRESENTING A CHANNEL ESTIMATION METHOD WITH CONSIDERING THE CARRIER FREQUENCY OFFSET BASED ON COMPARATIVE METHODS IN MIMO-OFDM SYSTEMS

摘要

The aim of this survey is to investigate channel estimation methods with carrier frequency offset based on comparative methods in MIM0-0FDM.According to this, using maximum likelihood estimation algorithm (MLE), the carrier frequency offset (CFO) can be estimated.According to this, with investigating the channel estimation method, we will design optimum training courses for these systems and will introduce related comparative methods based on LMS algorithm.The efficiency of suggested LMS algorithm can be investigated with simulation and the results of estimation will come to a comparison.
