SC-FDE系统中改进的粗定时同步技术
Improved Coarse Timing Synchronization Technology in SC-FDE System
摘要
Abstract
This paper proposes an improved coarse timing synchronization method by altering the structure of training symbols and selecting special training sequences. The improved coarse synchronization algorithm is applied to Single Carrier Frequency Domain Equalization(SC-FDE)system in aeronautical channel of different scenarios. Simulation results show that the proposed method solves the problem about the plateau of timing metric in traditional coarse synchronization algorithm——Schmidl & Cox algorithm, and the mean of timing estimation offset is close to zero. This method gains better effect and accuracy of timing synchronization.关键词
