Cell splitting based on active antennas: Performance assessment for LTE system

Abstract

The adaptive beamforming technology is an important tool in modern communication systems like LTE-Advanced in order to enhance system capacity. Beamforming techniques allow to direct the signal toward the useful users while decreasing at the same time the interference toward and from the users of the neighbouring cells. The aim of this document is to study the impact of both vertical and horizontal beamforming on LTE system performance using Active Antenna System (AAS).
