多用户空时分组编码系统存在译码复杂度高的问题。为了降低系统译码复杂度并保证较好的系统性能,将低复杂度的迫整检测算法用于多用户空时分组编码中,并基于等效噪声功率最小化原则获取了迫整检测的差错概率上界。为了解决迫整检测的多用户空时分组编码设计问题,提出了基于迫整检测的全分集多用户空时分组编码设计准则,证明只要每个用户的空时分组编码方案均满足非零奇异值特性,则多用户空时分组编码可获得满分集增益,且其编码增益与最小奇异值有关。仿真结果表明,满足设计准则的空时分组编码方案能够获得满分集增益。
Multi-user space time block code systems have the problem of high decoding complexity.To ensure good system performance with low decoding complexity at the same time
low complexity integer-forcing (IF) detection algorithm was applied to multi-user space time block code.Then the upper bound of error probability for IF detection was derived by minimizing the equivalent noise power.To obtain good multi-user space time block code when decoded with IF detection
a full-diversity design criterion was proposed.It was proved that full diversity could be achieved if every user’s space time block code had property of non-vanishing singular value.Simulation result shows that the code gain is found related to the minimum singular value.
