| 摘 要： | 基于Jing-Hassibi的合作分集协议和Rajan等人的普通非正交放大传送（GNAF）协议,提出了具有完全分集和最大似然译码复杂度低的分布空时编码（DSTC）。这些编码是四次群最大似然可译分布空时编码,并且功率在中继之间随时间均匀分布。仿真结果显示这种编码具有较好的性能。

| Abstract: | A construction of a new family of Distributed Space-Time Codes(DSTC) having full diversity and low Maximum Likelihood decoding complexity is provided,based on the cooperative diversity protocols of Jing-Hassibi and the Generalized Non-orthogonal Amplify and Forward(GNAF)protocol of Rajan et al.These codes are four-group ML decodable and have uniform distribution of power among the relays as well as in time.Simulation results indicate that these codes have good performance. |

| Keywords: | cooperative communication Distributed Space-Time Code four-group Maximum Likelihood |
