摘要 以长期演进(LTE)上行链路单载波频分多址(SC-FDMA)传输方案为基础,提出了一种基于用户协作的小区间干扰抑制传输方案。该方案采用译码转发中继工作方式,位于相邻小区边缘的两用户互为中继相互协作,在3个时隙内完成用户终端到基站的信息传输。仿真研究表明:该方案能够有效抑制小区间用户共信道干扰,同时充分利用用户协作所提供的空间分集增益提高小区边缘用户链路传输可靠性。此外,该方案所采用的块空时分组编码(B-STBC)能够很好地保持用户终端发射信号的低峰均比特性。 An inter-cell interference (ICI) suppression scheme based on cooperation transmission for LTE (Long Term Evolution) uplink SC-FDMA (Single Carrier Frequency Division Multiple Access) systems is proposed. By letting a user be a relay of the other one, the two users at the edge of neighboring cells cooperate in decode-and-forward mode. Under this structure, the two users could fulfill cooperative transmission from UE to base-station in three time slots. The simulation results show that the proposed scheme could suppress the ICI effectively, and exploit spatial diversity gain to improve the link reliability of cell-edge users. Moreover, with B-STBC (Block-Space-Time Block Code) the transmission signal could keep the characteristic of low PAPR (Peak to Average Power Ratio).
