基于 CAZAC 序列的 MIMO-OFDM 定时同步算法
MIMO-OFDM Timing Synchronization Algorithm Based on the CAZAC Sequence
摘要
Abstract
A new synchronization method for MIMO-OFDM systems with CAZAC sequence was proposed.Frame tim-ing objective functions were sharpen by using CAZAC Sequence,and its accuracy was also improved.Combing frame and symbol synchronization,only one step was needed for timing algorithm.The computation load was reduced and the first channel path was defined accurately.Integral frequency offset correction was achieved in time domain with a lower complexi-ty.The proposed scheme can not only improve the precision of synchronization,but also reduce the complexity greatly.Simu-lation result shows it has a better performance than the traditional method especially in Rayleigh fading channel.关键词
