摘要
基于连续OFDM符号上的导频子载波,给出了联合频率偏移纠正和信道估计方法.相比之下,这种方法没有频谱效率损失,在载波频率偏移不大的情况下不失为一种有效的克服载波频率偏移的方法.
In this paper, the pilot subcarriers on two consecutive OFDM symbols are utilized for joint frequency offset correction and channel estimation. There is no spectrum efficiency loss compared to the SIC method and it will make an efficient method to combat frequency offset in the case that the offset is not too large.
