What is the purpose of having Multi-Antenna processing in LTE?


LTE is supposed to have high data rate and throughput compared to previous technologies. For this reason and purpose LTE supports several different multi-antenna techniques and processing in order to enable high spectral efficiencies in a wide range of scenarios.

Mainly there are three multi-antenna processing schemes which run in LTE. There are different flavors of these three schemes. However, the underlying concept for different schemes originates from these three schemes namely.

  • Directivity
  • Diversity
  • Spatial Multiplexing
