DEVELOPMENT OF AN IMPROVED PILOT DECONTAMINATION SCHEME USING ORTHOGONAL UPLINK PILOT SEQUENCE BASED ON LARGE SCALE FADING MASSIVE MIMO SYSTEMS

S. M. Atiku^*, Abdoulie M. S. Tekanyi, K. A. Abubilal, H. A. Abdulkareem, U. F. Abdu-Ague

Pilot contamination (PC) is the major challenge in Massive Multiple Input Multiple Output (M-MIMO) systems of work of previous researchers because it reduces the achievement of numerous benefits of the M-MIMO system. In this proposed scheme, users are classified into center cell and edge cell users based on their large-scale fading. The center cell...
