TLDR
The analysis model is confined to 3GPP downlink transmission in which the single user (SU) and multi-user (MU) spatial division multiplexing (SDM) MIMO schemes are investigated, and it is found that the outage probability for systems using the SU-MIMO scheme is larger than the one for the MU-M IMO scheme.Abstract:
This paper derives mathematical expressions for the SINR distribution in systems with linearly precoded multiuser MIMO and frequency domain packet scheduling. The packet scheduler is able to exploit the available multiuser diversity in both time, frequency and spatial domains. Our analysis model is confined to 3GPP downlink transmission in which we specifically investigate the single user (SU) and multi-user (MU) spatial division multiplexing (SDM) MIMO schemes. From the analytical results we find that the outage probability for systems using the SU-MIMO scheme is larger than the one for the MU-MIMO scheme. Also, in comparison to systems without precoding, linear precoding can improve the outage probability.read more

Analysis of Multiuser Cellular Systems Over Heterogeneous Channels
TL;DR: It is mathematically proven that common correlation patterns for each terminal predicts lower ergodic sum spectral efficiencies in comparison to terminal specific correlation patterns, which demonstrates the impact of space-constrained ULAs on the MU-MIMO system performance.

Eigenvalues and condition numbers of random matrices
TL;DR: For real or complex matrices with elements from a standard normal distribution, the condition number should be given given a random matrix, and as mentioned in this paper showed that condition number is not the right condition number for any real matrix.
