Description: 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 extremely sensitive to begin with the initial guidance as to detect the signal. The later focus on the blind channel estimation ~ The two papers is a blind channel Technical ~ help you learn more knowledge Platform: |

Description: 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
symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the
proposed method employs a two stage estimator, which greatly minimize the computational complexity. ,A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this
