摘要

A non-reused pilot (NRP) design scheme is presented for Large-scale multi-cell multiuser multiple-input multiple-output (LS-MIMO) systems. As the users at the cell edge suffer from severe pilot contamination (PC), the pilot design based on Chu sequences for two kinds of users is considered. The users in each cell are divided into center users and edge users according to the large-scale fading coefficients. The proposed pilot design scheme can reduce inter-cell interference of center users and improve the performance of edge users, whereby assigning phase shifted pilot groups to center users in adjacent cells and orthogonal pilot group to edge users in all cells.
