| 摘 要： | 未来的移动通信系统LTE的下行链路将广泛采用MIMO-OFDM技术。基于MIMO-OFDM系统的表达式和信道模型,以及Zadoff-Chu序列,提出了一种等周期的伪叠加Zadoff-Chu序列的集中式和分布式MIMO同步算法,并进行了仿真。仿真结果表明该算法能够准确地进行符号时间同步,验证了所提出符号同步算法的有效性。

| Abstract: | The downlink of future mobile communication systems(LTE)will widely adopt the MIMO-OFDM technology.Based on the channel expression and models of MIMO-OFDM system,as well as Zadoff-Chu sequence,centralized and distributed MIMO synchronization algorithms of periodical pseudo-superposition of Zadoff-Chu sequence are proposed and simulated.The simulation results show that the algorithm can correct for symbol time synchronization,verify that the proposed symbol synchronization algorithm with effectiveness. |
