摘要
波束赋形天线因具有大覆盖范围和高空间分集增益的特性,受到了广泛关注。在波束赋形系统中,指向性波束的同步是实现通信的前提,也是需要克服的挑战之一。文中提出基于同步序列设计的波束同步方法,对同步序列的帧结构、序列种类和序列模式进行详细的设计。仿真结果表明同步序列具有良好的检测性能,与传统方向估计相比,算法显著降低了硬件资源开销,是一种波束同步的低复杂度实现方案。
Due to the large cover range and the space diversity ol beamiorming antenna, it has attracted the extensive attention in recent year. The beam synchronization is the precondition ol beamforming wireless system, and it ’ s also a big challenge. This paper proposes a beam synchronization algorithmbased on synchronization sequence. A n d the paper presents the detail description of frame structure,sequence type and sequence pattern in the algorithm. The simulation results show that the detection ofsynchronization sequence has good performance. Comparing to the traditional direction of arrivalalgorithm, the proposed algorithm significantly lowers the resource cost in the hardware. It ’ s a low complexity algorithm for beam synchronization.
