Channel Estimation in Spatially Correlated High Mobility MIMO-OFDM Systems
MIMO-OFDM is a transmission method very sensitive to the channel time-variations arising in high mobility scenarios due to the appearance of inter-carrier interference (ICI). In this paper we propose an algorithm for channel estimation in MIMO-OFDM systems that uses a Basis Expansion Model that exploits temporal, frequency and spatial correlations within the wireless channel in high mobility sc...
متن کاملComplexity-Reduced Channel Estimation in Spatially Correlated MIMO-OFDM Systems
The performance of a MIMO-OFDM system significantly depends upon the accuracy of the channel impulse response (CIR) estimates. In the presence of correlation between the CIRs of the transmit or receive antennas, it is desirable to exploit this correlation to improve the performance of CIR estimation. In this letter, we propose a low-complexity channel estimation filter composed of four concaten...
متن کاملGeometric Modelling of a Spatially Correlated Mimo Fading Channel
For a single antenna channel, Shannon’s classical capacity formula predicts a capacity increase of approximately 1 bit/cycle for every 3 dB increase in signal to noise ratio (SNR). Consequently in multiple antenna arrays, with n antenna elements, the increase in capacity can be in the order of the number of antenna elements, n more bits/cycle for each 3dB increase in SNR. This tremendous gain i...
متن کاملPilot signal design for coordinated transmission in massive MIMO systems
Massive multi-input multi-output (m-MIMO) and coordinated multipoint transmission (CoMP) are quite feasible techniques to improve the spectral efficiency in next generation wireless communication systems. It is of great concern to accurately estimate channel state information (CSI) of all base stations (BSs) involved in CoMP. Muting may be applied to improve the CSI estimation, which can reduce...
متن کاملTransmit Signal Design for MIMO Radar and Massive MIMO Channel Estimation
Duly, Andrew Jason Ph.D., Purdue University, December 2013. Transmit Signal Design for MIMO Radar and Massive MIMO Channel Estimation. Major Professors: David J. Love and James V. Krogmeier. The widespread availability of antenna arrays and the capability to independently control signal emissions from each antenna make transmit signal design increasingly important for radar and wireless communi...
