dc.description.abstract
Channel estimation is a key aspect for the
performance of the physical layer in all MIMO-OFDM
systems. In order to obtain realistic performance assessments
from the LTE link level simulator, channel estimation errors
must be taken into account. Implementing a detailed channel
estimation algorithm may lead to long simulation time, in
particular for wideband MIMO transmission modes where
many channels have to be estimated, and for procedures like
Wiener filtering which require matrix multiplications. In this
paper we propose to simulate channel estimation errors by a
Gaussian additive noise error model. The noise variance of the
model is calibrated as a function of the received SNR for
different channel models and Doppler spreads. The model is
validated by comparing the BLER curves obtained with the
model with the curves obtained when using real channel
estimation.
