Performance Comparison among MIMO Techniques at Different Interference Levels for LTE

MIMO technique (multi antenna transmission and reception) is a key feature of long term evolution (LTE) which ensures higher spectral efficiency and better multiuser flexibility making a cellular system spectrally efficient but inherently densely populated and interference-limited. Performance of spatial multiplexing MIMO techniques degrades with the introduction of interference in the system. To choose optimum MIMO mode it is worthwhile to analyze the UE (user equipment) throughput under different interference scenarios before physical implementation of a system. This paper contains a comparative study of MIMO technique performances in terms of UE throughput under two different UE speeds and interference scenarios.
