REVIEW OF THE PILOT CONTAMINATION PROBLEM FOR MASSIVE MIMO AND POSSIBLE SOLUTION

With the increasing demands of data communication speed for different type of data transmission, many revolutions occur with time in wireless communication system. The use of MIMO for wireless data transmission has proven itself for enhancing the capacity of data transmission. The mobile network based on the cell structure also uses the MIMO techniques. Further research in the field of massive MIMO has started for faithful data transmission. The enhancement by massive MIMO encounters many problems related to the implementation. One of the biggest challenges for massive MIMO is the pilot contamination. In this paper, Massive MIMO along with the pilot contamination is described. The research work presented by the researcher on this topic has summarized which also includes the possible solution to this problem.
