In this paper, we consider downlink multi-user
MIMO transmission in massive MIMO systems, assuming massive
amount of antennas at transmitter- as well as receiverside.
We investigate the performance of several linear MIMO
transceiver architectures of comparatively low complexity, since
non-linear schemes of high complexity (e.g., maximum likelihood
detection) appear infeasible with large numbers of transmit
and/or receive antennas. The focus of our investigation lies on the
impact of spatial antenna correlation on the achievable rate of the
considered schemes. We derive achievable rate upper bounds that
facilitate interpretation and explanation of performance losses
observed with increasing antenna correlation and with growing
number of antennas and spatially multiplexed users. We identify
favourable combinations of low complexity transmitter/receiver
filters and show that the impact of antenna correlation strongly
depends on the applied transceiver architecture.
