中文摘要：

为了解决下一代演进移动通信系统在异构网场景由于小区ID数量不足导致的小区ID模糊问题及小区间干扰问题,提出了一种主同步信道和序列设计方法。其中主同步信道基于分级和非分级的混合结构,主同步序列由具有恒包络零自相关特性的Bj rck序列的修正序列组成。仿真结果表明,与IEEE 802.16m系统相比,设计的主同步信道由于采用的序列具有更低的相关值和峰均比,在小区间干扰场景具有更小的误检测概率。

英文摘要：

An optimum primary- synchronization channel （P - SCH） design is presented for the evolved next generation mobile communication systems in heterogeneous network scenario where adequate cell IDs are needed to avoid the cell ID confusion and inter-cell interference. The proposed P- SCH assumes a hierarchical struc- ture, and the sequences are modified BjSrck CAZAC sequences. Simulation results demonstrate that the new se- quences with lower Peak Average Power Ratio（PAPR） have good correlation properties and cell search perfor- mance compared with IEEE 802.16m system.
