ABSTRACT
In this paper, we analyzed a numerical evaluation of the performance of MIMO radio systems in the LTE
network environment. Downlink physical layer of the OFDM-MIMO based radio interface is considered
for system model and a theoretical analysis of the bit error rate of the two space-time codes (SFBC 2×1
and FSTD 4×2 codes are adopted by the LTE norm as a function of the signal to noise ratio. Analytical
expressions are given for transmission over a Rayleigh channel without spatial correlation which is then
compared with Monte-Carlo simulations. Further evaluated channel capacity and simulation results show
throughput almost reaches to the capacity limit.
