This paper presents an SINR prediction model for
LTE systems with the aim of improving the accuracy of physical
layer models used for higher-than-physical-level simulations.
This physical layer SINR abstraction for zero-forcing receivers
takes channel estimation errors into account. It allows for the
calculation of the post-equalization receive SINR of an LTE
MIMO transmission on a per-layer and subcarrier basis. This
estimate is further used as input for a link performance model
to accurately predict the receiver throughput. The accuracy
of the model is validated by simulations for 2x 2 and 4 x4
MIMO antenna configurations with different levels of spatial
multiplexing employing also the precoding matrices defined in
the LTE standard. Memory requirements and complexity for the
model are quantified as well. The whole simulation environment
together with the fully reproducible results of this paper are
made available for download from our homepage.
