Title

Mitigating the pilot contamination for uplink massive MIMO systems

Abstract

Multi-cell Massive MIMO System utilizes a large number of antennas in a base station that serves a group of users at the same time, suffers from pilot contamination(PC) due to the reuse of pilots in adjacent cells that isn't able to avoid. In this paper, mitigating the pilot contamination based on soft pilot reuse scheme and weighted graph coloring scheme. All users in a cell are foremost divided into cell-center users and cell-edged users. By choosing the best pilots we tend to propose a suboptimal allocation algorithm by exploitation with optimum conditions and weighted graph color methodology is applied. Simulation results show that the proposed scheme alleviating the pilot contamination significantly compared with existing schemes.

Key Words

Pilot contamination, Massive MIMO, Soft pilot reuse, weighted graph coloring
