针对密集多径情况下超宽带信号的捕获,采用分块与比特反转搜索相结合并加以改进,得到了改进的比特反转搜索算法,仿真结果表明其性能较比特反转搜索算法有较大改善,尤其在搜索间隔较小时性能更好。
In this paper, we propose an improved rapid timing acquisition algorithm for UWB, which combine the block method and bit reversal search. The simulation indicate the new algorithm improve acquisition performance. Especially the search interval is small, the bit reversal block search is able to achieve good performance.
