With the widespread growth of urban environments and the appearance of vehicle-to-X access communications, new techniques have emerged to overcome this densification matter. One promising technology is the Full-Dimension MIMO (FD-MIMO), which by using 2-dimensional planar antenna arrays, can model the beams and steer them not only horizontally, but also in the vertical domain. This is called 3D beamforming.
As a generalization of beamforming in multi-antenna wireless communications, three different non-codebook based precoders have been studied and compared in this thesis. These are, the Maximum Ratio Transmission (MRT), the so-called Geometry Based and the Exhaustive Search over azimuth precoders.
Using the Vienna LTE-A Downlink System Level Simulator, several simulations have been performed to evaluate the performance of the aforementioned scenarios. These are the comparison between Line-of-Sight (LOS) and Non-Line-of Sight
(NLOS) propagation conditions and the inclusion of an uncertainty area around the users, accounting for moving users. All these contrasting scenarios will help the reader to understand the pros and cons of the three aforementioned precoding methods.
