基于 SC －FDE 的频率选择性衰落信道中的空时分组编码系统性能研究

摘要

In the frequency selective fading channel,the orthogo-nal space -time block code with single -carrier frequency domain e-qualization (OSTBC -SCFDE)system can effectively combat the fre-quency selective fading,and achieve full diversity gain.It has attracted widespread attention.However,it does not achieve full rate transmis-sion when more than two transmit antennas.In order to overcome the shortcomings of the program,this paper studies the rotation matrix quasi orthogonal space -time block code with single -carrier frequency do-main equalizaton(RM-QOSTBC -SCFDE).Simulation results show that when the number of transmit antennas is 4,this program not only a-chieve full rate transmission but also get a high diversity gain.
