摘要 多输入多输出技术(MIMO)与正交频分复用技术(OFDM)相结合,可以提高无线通信系统在选择性衰落信道中的传输性能,满足新一代移动通信系统的要求。利用超正交空时网格编码(SOSTTC)结构,结合OFDM的优势,构建了一个SOSTTC-OFDM系统,进行了SOSTTC-OFDM系统的仿真实验。通过仿真证明了SOSTTC-OFDM系统具有很好的抗衰落性能,并且采用SOSTTC可以使系统获得更好的分集增益和编码增益。 The combination of MIMO with OFDM could improve the capability of wireless communication systems in frequency-selective fading channels,and thus meet the requirement of new-generation mobile communication system.Based on the structure of （SOSTTC,super-orthogonal space-time trellis codes）,and in integration of OFDM superiority,a SOSTTC-OFDM system is constructed.The simulation with MATLAB on this system shows that SOSTTC-OFDM system has good characteristics in the fast fading channels,and with SOSTTT,could achieve much better diversity gain and coding gain.
