Estimation of carrier frequency offsets for MIMO systems with distributed transmit antennas

Abstract: 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. The channel is supposed to be frequency flat, and the macroscopic fading is also taken into consideration. A carrie… Show more

“…An introduction to the concept and key technologies of cooperative DAS systems can be found in [91], which shows that a DAS with a cooperative transmission scheme can provide very promising performance enhancements in capacity and transmit power efficiency. Based on the ML algorithm, the authors in [92] investigated the carrier frequency offsets in MIMO systems with distributed transmit antennas, where the received antennas were assumed to be centralized. Spectrum efficiency, as a significant performance metric, is investigated analytically in closed-form for D-MIMO cellular systems under a composite fading channel [93].…”
