  • 摘要: 針對大規(guī)模多輸入多輸出(MIMO)系統(tǒng)中存在的導頻污染問題，該文提出一種動態(tài)導頻分配方案。所提方案利用目標小區(qū)與干擾小區(qū)用戶之間的信號干擾強度差將干擾小區(qū)分為Uin和Uout兩類，并對Uin中的用戶進行最優(yōu)導頻分配，Uout中的用戶進行隨機導頻分配來提升系統(tǒng)的平均下行可達和速率。同時，在存在額外正交導頻組的情況下對所提方案做了進一步優(yōu)化。仿真結(jié)果表明，所提的動態(tài)導頻分配方案能夠有效地提升大規(guī)模MIMO系統(tǒng)的性能。
    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.
