摘　　要：无线通信技术正加速向更高端的4G技术演进,基于TD-LTE与TD-SCDMA的物理帧结构相容,该文提出一种低复杂度的TD-SCDMA下行同步检测机制,并采用软件仿真的方法设计和测试不同SNR和不同量化字长的TD-SCDMA下行链路同步性能,得出所需要的最佳量化字长。与传统的非相干方案相比,该文算法具有较好的性能和较低的复杂度等优点。At present, wireless communication technology is rapidly evolving to the 4G technology the physical frame structure of TD-LTE technology being same to TD-SCDMA, we propose a low Btlsed Oil COrn method of TD-SCDMA downlink synchronization detection and the performance of TD-SCDMA downlin chronization, with different quantization word length and SNR, is designed and tested by using software lation： Furthermore, the requ od, this algorithm has higher ired minimized word length is found. performance lower complexity Compared to traditional non-coherent plexity k syn- simulation： Furtlaermore, th~ required minimized word length is found. Compared to traditional non-coherent meth- od, this algorithm has higher performance and lower complexity.
