超大规模MIMO-OTFS系统上行辅助的下行信道估计方法OA
Uplink assisted downlink channel estimation method of extra-large scale MIMO-OTFS system
针对超大规模多输入多输出(MIMO,multiple-input multiple-output)正交时频空间(OTFS,orthogonal time frequency space)系统,提出了一种适用于高速移动场景的低复杂度下行信道估计方法.不同于现有研究,该方法考虑了超大规模MIMO-OTFS系统显著的空间非平稳特性,基于可视路径区域提出了一种低复杂度的增强型稀疏正交匹配追踪算法,利用频分双工(FDD,frequency-division…查看全部>>
A low complexity downlink channel estimation method for high-speed mobile scenarios was proposed for the extra-large scale multiple-input multiple-output(MIMO)orthogonal time-frequency space(OTFS)system.Different from the existing studies,the proposed method considers the significant spatial non-stationary characteristics of ex-tra-large scale MIMO-OTFS system.Based on the visible path region,an enhanced sparse orthogonal matching pursuit(OMP)algorithm with …查看全部>>
