In this paper, we address the problem of carrier frequency offset estimation for multiple-input multiple-output (MIMO) correlated fading channels. A maximum likelihood (ML) carrier frequency offset estimator based on the average likelihood function is proposed, which can make use of the channel correlation information by averaging the conditional likelihood function over all realizations of the channel...
The problem of estimating the carrier frequency offsets in Multiple-Input Multiple-Output (MIMO) systems with distributed transmit antennas is addressed. It is supposed that the transmit antennas are distributed while the receive antennas are still centralized, and the general case where both the time delays and the frequency offsets are possibly different for each transmit antenna is considered....
