OFDM(Orthogonal frequency-division multiplexing)意即正交頻分複用技術對頻率偏移極為敏感,初期皆以導引信號作為偵測. 後期則著重在盲通道估測~此兩篇論文是盲通道的技術~有助於你學習更多知識 -OFDM (Orthogonal frequency-division multiplexing) means orthogonal frequency division multiplexing frequency offset pairs are

A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM sy

提出一种全新的子载波调制方式盲识别算法,该算法利用ＯＦＤＭ子载波组的统计特性,然后通过推导得到新的基于混合高阶矩的特征量,使得到新的特征量不受信噪比、载波频偏与相位偏移的影响。 -Proposed a new sub-carrier modulation count Blind Identification Method, the method using the statistical characteristics of the OFDM sub-carrier group, an
