Abstract

Abstract

A dynamic pilot allocation scheme is proposed in case of the pilot contamination existing in massive MIMO system. Based on the signal to interference difference between the aim cell user and the interference cell user, the interference cell is divided intoUin and Uout. Specifically, in order to improve the average downlink achievable sum rates, the users in theUin are operated with the optimal pilot allocation, and the users in theUout are operated with the random pilot allocation. Simultaneously, the proposed pilot allocation scheme is further optimized with an extral set of orthogonal pilots. Simulation results show that the proposed dynamic pilot allocation scheme can enhance the downlink performance of the massive MIMO system effectively.
