In practical multiple-input multiple-output (MIMO) systems, due to the close proximity among the antennas, the channels between different transmit and receive antennas are spatially correlated. Besides spatial correlation, closely placed antennas also experience mutual coupling among the antennas, which is due to the interaction of electro-magnetic fields at different antennas. In this paper, we present...
In the uplink of multi-user multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems, there are multiple carrier frequency offsets (CFO's) from the multiple users. In this paper, we study algorithms to estimate these multiple CFO values. We first derive the maximum likelihood (ML) estimator and show that the complexity of the ML estimator increases exponentially...
