OFDM Time and Frequency Synchronization Based on Training Sequence with Polarity
Xiaomin Li · Journal of Zhengzhou University · 2012
Follow the H.Minn algorithm,put forward an OFDM time and frequency synchronization method based on training sequence with polarity,summarize the time and frequency estimation unified formula.The modified algorithm's timing curve have only one peak,overcome SC algorithm's timing plateau and H.Minn algorithm's multi-peak,thus improve the accuracy of timing synchronization,the characteristics of its structure also provides flexibility for the frequency estimation,further improve the frequency estimation performance.
