摘　　要：针对频率选择性衰落下的多中继分布式空频编码协同通信系统,提出了一种基于球形译码的频域符号检测算法。理论分析和仿真结果表明,该检测算法不仅获得了与最大似然(ML)检测算法相同的误符号率性能,而且显著降低了分布式空频编码协同通信系统检测算法的复杂度,具有较高的实用价值。A sphere decoding based detection algorithm is proposed for distributed space-frequency coded cooperative communication systems with multiple relay nodes over frequency-selective fading channels. The theoretical analysis and the simulation results show that the proposed detection algorithm can not only achieve the same symbol error rate （SER） performance as the maximum likelihood （ML） detection algorithm, but also can reduce the algorithm complexity, so it has the higher practicality.
