TD-LTE自适应辅同步信号检测算法与仿真实现
Simulation and realization on adaptive secondary synchronization signal detection in TD-LTE system
摘要
Abstract
This paper introduced the detection method of the adaptive secondary synchronization signal in the LTE-TDD system. Firstly, using adaptive feedback method to correct the frequency-domain channel impulsed response which estimated by the primary synchronization signal. Through the coherent detection, enormously improved the detection success rate for secondary synchronization signal. Moreover, the method of using indices to detect secondary synchronization sequences greatly reduced the computational complexity. Both theory analysis and simulation results show that proposed algorithm has good performance in different channel conditions, and can satisfy the performance demand by the detection of secondary synchronization signal in TD-LTE system.关键词
