We compare the performance of the downlink of a 3GPP UTRAN Long Term Evolution (LTE) system with multi-user (MU) multiple input multiple output (MIMO) support and channel state information (CSI) feedback to a standard MU-MIMO LTE system utilizing channel quality indicator (CQI) feedback only. For the latter case, we propose an efficient method for estimating the appropriate MU-MIMO transmission parameters...
We analyze the capacity of multiple-input multiple-output (MIMO) systems employing orthogonal space-time block codes (STBC) in spatially correlated Nakagami-m fading channels under different power and rate adaptation policies. In this regard, we assume that partial channel state information (CSI) in form of the instantaneous post-processing signal-to-noise ratio (SNR) at the receiver-side is available...
