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。 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.
