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.
Based on the pilot sub-carriers on the continuous OFDM symbols, a joint frequency offset correction and channel estimation method is given, which is compared with no loss of spectrum efficiency and is a lossless carrier frequency offset Effective way to overcome the carrier frequency offset.
