本文讨论了不完美的同步D-STBC增量中继相结合时的影响。为了抑制这种影响，提出了一种新的检测方案，该方案保留了STBC原理的两个关键特征：简单性（即线性计算复杂度）和最优性（即最大似然性）。这两个特点使得新的检测器非常适合低功耗无线网络（例如传感器网络）。
This paper addresses the impact of imperfect synchronisation on D-STBC when combined with incremental relay. To suppress such an impact, a novel detection scheme is proposed, which retains the two key features of the STBC principle: simplicity (i.e. linear computational complexity), and optimality (i.e. maximum likelihood). These two features make the new detector very suitable for low power wireless networks (e.g. sensor networks).
