摘要
文章针对于采用正交空时分组码的多天线超宽带(UWB)通信系统,提出了一种基于训练符号的低复杂度的同步方法。利用巧妙设计的训练符号方案,同步捕获可以通过在接收信号间作滑动平均来实现。该方法所涉及的操作是积分-堆存运算,复杂度较低;并且具有较快的同步捕获速度。
In this paper,a low-complexity training-based synchronization method is proposed for multi-antennae ultra-wideband（UWB） communications wedded with space-time block codes（STBC）.By judiciously designing training scheme,synchronization can be achieved by performing sliding correlation among received waveform.The proposed method requires only integrate-dump operations and thus is of low-complexity.Furthermore,several training symbols are sufficient for timing acquisition.
