MIMO-OFDM Channel Estimation in the Presence of Carrier Frequency Offset
EURASIP Journal on Applied Signal Processing 2005: 4, 1-7,-0001,():
A multiple-input multiple-output (MIMO) wireless communication system with orthogonal frequency division multiplexing(OFDM) is expected to be a promising scheme. However, the estimation of the carrier frequency offset (CFO) and the channelparameters is a great challenging task. In this paper, a maximum-likelihood-(ML-) based algorithm is proposed to jointly estimate the frequency-selective channels and the CFO in MIMO-OFDM by using a block-type pilot. The proposed algorithm is capable of dealing with the CFO range nearly
